Non-playable character

Non-playable characters (NPCs) are characters that cannot be played by the player from the game's start. They are in every Sim game: The Sims, The Sims 2, The Sims 3, and The Sims 4. (While townies are considered to be a class of NPC, they are largely outside the scope of this article.)

There are two main types of NPC; ones that through relationships and/or simple cheats will be able to be playable characters without any programming errors and ones that were specifically not meant to be played. In The Sims, all NPCs, other than the townies, are of this second type. Sims cannot build relationships with them, and most either can't be interacted with at all, or only have a few interactions that are related to their function. In The Sims 2 and The Sims 3, most NPCs can be interacted with, at least when they're not on the job, and Sims can build relationships with them. Also, some may appear on community lots, where they can essentially be treated as townies.

The Sims
Except for the townies, NPCs in The Sims are not full-fledged Sims. They have special character files which contain their names and define their appearance, and which control what they can do and how (or whether) they can be interacted with.

Service
These NPCs can be hired through the phone to perform specific services around the house.
 * Maid: When hired, Brigit the Maid will visit everyday to clean the lot. She will clean dishes, pick up trash, mop up puddles, flush toilets, and make beds.
 * Gardener: Every three days Gardener Gloria will arrive to water indoor and outdoor plants.
 * Repairman: When summoned Repairman Bruno fixes broken objects, unclogs toilets, and even replaces light bulbs.
 * Pizza deliverer: Offers a one-off pizza delivery service to your Sims' home when called. Oddly, his dialogue box reveals his name to be "Freddy the Pizza Delivery Dude", but if Hot Date is installed, his rollover text will read "Pizza Delivery Dude Dale". This contradiction remains unfixed in the final version of the game.
 * Clown catcher: Clown Cleanser Sean or Clown Cleanser Shawn can be summoned if the Tragic Clown is on the lot and will capture and remove him. They will also repossess the Tragic Clown painting to ensure he doesn't return.
 * Caterer: Yves the Caterer can be hired for parties, and will refill the punch bowl, restock the buffet table, clear empty plates and socialise with guests.
 * Animal control: Animal Control Evan can be hired to remove El Bandito or Henri LeStanc. He cannot be called unless one of the two is on the lot.
 * Massage: Walther Masseur or Inga Masseuse can be hired to give massages at a massage table. They will also operate any massage tables located in Studio Town.
 * Butler: Alfred the Butler works from 7am until 12am every day and will cook, clean and look after babies and pets. He may also hire additional service NPCs to assist him, or activate Servo when needed.

Emergency service
These NPCs can be called through the phone and will be automatically summoned if the appropriate alarm is triggered. They will fine Sims for false alarms.
 * Firefighter: Firefighter Freddy will automatically be summoned if a fire alarm is triggered. He can also be called from the phone, and will fine §100 for false alarms.
 * Police: Michelle the Policewoman will arrive instantly when the burglar alarm goes off or when Sims call her when a burglar appears. She always apprehends the burglar successfully. Potion Enforcement Agent Angie will appear if The "Concoctanation Station" is used during school hours and fine the Sim who used it for causing an environmental hazard.

Public service
These NPCs will perform their duties automatically and cannot be interacted with by other Sims.
 * Paper girl: Nancy the Paper Girl appears on the lot at 9am every morning to deliver the newspaper and tabloid. If a family has a dog, the dog may scare away the paper girl, but she will make her deliveries first.
 * Mail carrier: Carrie the Mail Carrier appears every 3 days to deliver bills, which she places in the mailbox.
 * Repo-man: If bills go unpaid for any reason, Bud the Repo-man will arrive and repossess objects from the lot to cover the value of the bills.
 * Social worker: If babies are not properly taken care of, Sylvia the Social Worker will appear to take them away.

Visitors
These NPCs will appear on the lot only during specific situations. Most cannot be interacted with beyond their limited role.
 * Burglar: Whenever every Sim on the lot is asleep, Some Sneaky Sim may sneak in and steal their possessions. Players can either have a Sim call the police, or buy an alarm. With the alarm installed, the police will arrive instantly. If the police are called over the phone, it may take too long for them to arrive, and the burglar may escape.
 * Grim Reaper: The Grim Reaper appears when a Sim dies to claim their remains. If Death is in a good mood however, another Sim can be directed to challenge him, although children can't plead with the Grim Reaper. If he accepts, he will either play rock, paper, scissors with or a shell game. If the Sim wins the game, the deceased is brought back to life for a second chance, but if the Sim loses, Death will either take the corpse or create a zombie. When the Sim is turned into a zombie, they will have no personality and their skin will be colored green.
 * Tragic Clown:, Sunny the Tragic Clown will visit depressed Sims who own the "Tragic Clown" painting in order to cheer them up. However, the Sims' moods will not improve as the Tragic Clown is also feeling miserable. The clown will usually walk around the house, and do nothing but cough and cry, and fail at any tricks (i.e., when he juggles, he hits himself with his bowling pins and when he blows up a balloon poodle, it will pop). He will leave when the depressed Sim's Fun need increases, or when the Tragic Clown painting is either sold or destroyed.
 * Santa Claus: If a Christmas tree and a plate of cookies are near a fireplace at midnight, Santa Claus will appear while the Sims are sleeping. He'll leave a small gift for each Sim in the household, plus an extra special present, which could be any item.
 * Entertainer: Chip the Dancer or Bunny the Dancer can be hired to emerge from the giant cake, and start entertaining party guests. There is a chance that the entertainer might stir jealousy from other Sims, and children will be shooed out of the room.
 * Mime: Gabby the Mime will show up at a party if it is going very badly. Like the Tragic Clown, he will try to raise everyone's mood, but isn't very good at it and may occasionally steal objects on the lot. He will leave only when the party gets better.
 * Party crasher: Pete Dropinsky or Paulette Dropinsky may arrive during mediocre to fairly good parties, and will socialize with other guests. They may possibly destroy objects on the lot.
 * Drew Carey: A real life celebrity who shows up as a reward for a great party.
 * Obsessed fan:, Sims can attract unwanted attention if they achieve 3 stars of fame or more. The obsessed fan will stalk the Sim wherever they go, at home or at work and leave 'special presents' for the Sims - black roses. He will also paw through garbage cans, and will steal any awards that Sims have won for acting, singing or modeling. Awards can be protected by placing them in a room with the Zeddy-Lock Celebrity Security Door, as the Obsessed Fan cannot go through that door. Lana or Kana can be asked to shoo the Obsessed Fan away if he appears in Studio Town or Vacation Island respectively.
 * Mystery Man: The Mystery Man will appear on all residential lots shortly after a family moves in, or when a family is loaded after installing Makin' Magic. He will leave a package containing magic-related objects and ingredients. He also appears on all Magic Town lots, where Sims can purchase or sell wands. The Mystery Man also acts as the Spellchecker, delivering citations to Sims who cast spells in front of non-magical Sims.

Wildlife

 * Bear: Claire the Bear will rummage through the garbage can (waking sleeping Sims), talk to teddy bears or cry if she sees a bearskin rug. With Makin' Magic she will appear to raid honey from a beehive if one is present on the lot. Claire may also appear on Downtown lots to raid picnic baskets.
 * Raccoon: El Bandito may randomly creep onto the lot during the middle of the night, rummaging through garbage cans and waking sleeping Sims. Sims can shoo him away, though he may not leave. Pet dogs may automatically attack El Bandito, causing him to leave, and Animal Control can be hired to remove him from the lot.
 * Skunk: Henri LeStanc will appear if the household has poor hygiene levels and wander around smelling flowers. His presence will decrease the Room motive and Sims who are sprayed by the skunk will have their hygiene motive fully depleted. Animal Control can be hired to remove him from the lot.
 * Dragon: These creatures can be purchased from Vicki Vampiress in Magic Town and once hatched can become pets for the household. Unlike regular pets however, they are not selectable or controllable in any capacity and may not behave as expected as a consequence. They require flowers to feed on but will otherwise care for themselves.

Summons
These NPCs can only appear after casting specific spells or charms or when activating certain objects. Once summoned, they will perform actions around the house for a period of time before dispersing.
 * Evil clone: Drinking a dark green potion from the chemistry set will spawn an evil duplicate of the Sim. The clone will use mean interactions with other Sims, causing their relationship with the original Sim to be lowered, until eventually leaving.
 * Frankenstein: Drinking a purple potion from the chemistry set will cause the Sim to turn into a monster, who will proceed to break objects on the lot and paint easels until the effects wear off.
 * Genie: The Genie can be summoned from his antique lamp once per day and will offer Sims a choice of wish from a random selection. Each wish has a potential good outcome and bad outcome.
 * Servo: This robot can be summoned from its pod and will clean the lot, garden, repair objects and entertain guests. Servo can also be asked to prepare food, though it is always of low quality and not very fulfilling. When its chores are completed it will return to its base station. The Butler will activate Servo to complete chores if its pod is present on the lot.
 * Campfire ghost: Green Beard the Ghost may appear when Sims with high Charisma skill tell stories around the campfire. He will scare the Sims sitting around the campfire.
 * Bonehilda: This skeleton maid can be summoned from the Skeleton Closet if a Sim knocks on the door. She will clean the lot, repair objects, bring in the newspaper and look after babies. She will return to the closet when her chores are completed. If Brigit the Maid sees Bonehilda roaming the lot she will quit her job in terror.
 * Invisible friend: Summoned with the Invisible Friend charm, they are visible only to the child that cast it. The Sim can talk to or play with the invisible friend, though if the charm backfires the invisible friend may insult, tease or kick the caster.
 * Clone: A non-evil clone can be produced with the Clone Drone charm who will go to work or school in place of the caster. The charm will backfire if the caster is hungry, causing the clone to appear and then spontaneously combust.
 * Wally and Molly O' Wisp: Brother and sister spirits who appear when the "Of House and Home" charm is used. Wally will quickly clean the house if summoned, while Molly will wreak havoc.
 * Gardening gnomes: When enchanted, Gnomes will come to life and take care of plants on the lot. After a period of time they will solidify again.
 * FlaminGoGo Dancers: When enchanted, flamingo sculptures will come to life and socialize with other Sims on the lot, making them potential party entertainers. After a period of time they will solidify again.

Community lot NPCs
All community lots in The Sims spawn a janitor, who does general clean-up and repair work on the lot. Community lots on Vacation Island, and in Studio Town and Magic Town, also spawn a "lot director" who can provide information about some aspects of gameplay. On Vacation Island lots, a costumed mascot will arrive in the morning and leave at night, and an indoors maid will appear if a hotel desk is present.

Staff
Most of these NPCs cannot be interacted with beyond their limited role and others cannot be interacted at all. Several of these characters are spawned only if a specific object is present on the lot.
 * Janitor: Janitor Sonya works Downtown; Janitor Tanya and Maid Marrion maintain Vacation Island; Tidy Heidi cleans Old Town community lots; Pristine Christine cleans lots in Studio Town and Bonehilda, Wandering Willow and Witty Washout in Magic Town.

 * Sideshow assistant: Works on the performance stage in Magic Town and will assist with the magic show. If the performing Sim is not skilled enough they will hurt her, prompting her to scream and assault them in anger. If the show is successful, she will bow at the end along with the performer and applaud them.
 * Summoned assistants: Glenda the Ghost, Gordon the Ghost and Someone's Mummy can all be summoned on the "Electro's Spooky Laboratory" stage in Magic Town. If the performer has high logic, the ghosts will fly around and the mummy will obey the caster's commands, dance to a piano tune, spin around and disappear.

 * Snake charmer: Nagganaste will appear on lots with a snake charming basket. Sims can pay him a fee to try charming the snake themselves, earning MagiCoins. While he is not a vendor, he will barter Snake Venom for Golden Thread.

Others

Sims can only use the View interaction on him, which will display a message reading "Thanks for playing The Sims."

The Sims 2
The Sims 2 NPCs are much more colorful. For starters, basic NPCs can be interacted with in the same ways that other Sims can, at least when they're not on the job. They can be talked to, befriended, invited over, married, etc. They can be male or female, and each has a different face, hair color and name. They generally make more logical decisions, though there are exceptions. A neighborhood will usually have three NPCs of any given type (maid, etc.). If an NPC dies, becomes playable or gets turned into a vampire or werewolf, a new NPC will be generated to take the old NPC's place, but some NPC's death can cause corruption. An off-duty NPC can become a witch, and an NPC who becomes a witch will continue to do their job, although they may wear either their uniforms or their witch clothes. When University is installed, every NPC and townie gets a memory of going to college, whether they did or not.

Some NPCs might corrupt the neighborhood, or even the entire game if they are made selectable, moved in, or changed in any way. Most of these unsafe NPCs have the [3] note.

Townies
Townies form the largest class of NPC. Townies wander around the neighborhood or randomly walk by Sims' houses. There are many types of Townies in The Sims 2: see Townie for more information.

Service NPCs
Service NPCs are NPCs that help Sims around the house.
 * Maids: Maids clean the house and do most of the housekeeping. They come every day.
 * Gardeners: Gardeners clean Sims' gardens, pull weeds, water flowers, trim shrubs, and rake falling leaves. They come every three days.
 * Nannies: Nannies take care of babies, toddlers, and children. The player can have them track the calling Sim's work schedule. It's important to hire a nanny if there's no teen or older Sim in the house, as the social worker will take children who are left unattended. Nannies are also needed when going to a community lot or going on vacation would leave children home alone.
 * Bartenders: Sims can hire a bartender if they have a bar in their home. They are paid by the hour. Bartenders are also Community Service NPCs. Bartenders working at home and community lots are different bartenders.
 * Exterminators: Whenever a Sim's house is infested with cockroaches, they can call an exterminator to get rid of them.
 * Repairmen: Sims can call a repairman to fix broken objects. They'll fix everything from clogged toilets to broken electronics. They even tune pianos. Whenever a Servo is broken and he/she lives alone, a repairman will automatically come to fix it.
 * Gypsy matchmakers: Gypsy matchmakers sell potions to Sims. Sims can buy love potions, or potions to cure Vampirism, Lycanthropy, PlantSimism, or Witchiness. Sims can also ask the Matchmaker for a blind date. In FreeTime, the Gypsy Matchmaker may deliver a Dusty Old Lamp to Sims with high enthusiasm in a hobby, and high Lifetime Aspiration.
 * Obedience trainers: Obedience trainers train adult pets and sell Lycanthropic-B potions.
 * Animal control officers: Animal control officers dress like police, and they're often mistaken for police officers. They come to bring newly adopted pets to the family, or take away pets that have been mistreated..
 * Butlers: Butlers take over almost all of the Service NPCs work. So, Sims no longer need to hire every single Service NPC for housekeeping. Butlers are very costly, so players should mind a family's budget before having them hire one. Butlers don't take care of some problems, such as cockroaches, fires, or burglars. Instead, they call the appropriate NPCs.
 * Landlords: Landlords are assumed to be the owners of the apartment lots. Sims can pay the weekly rent directly to the landlords or by using the mailbox. Sims can lower their rent by making friends with them. They will garden and clean the common area in an apartment lot.

Emergency NPCs
Emergency NPCs arrive immediately after Sims call them on the phone, or when summoned by an alarm.
 * Police: Police can apprehend a burglar, but are not always able to. They also appear when a Teen is caught sneaking out or a party lasts until midnight. Sims also need to call the police when their Teens or pets run away. In University, a police officer wearing a llama blazer will "arrest" Sims who are to be inducted into the Secret Society.
 * Firefighters: Firefighters are always able to put out fires, though when a fire is very large, they sometimes call for help from other firefighters.

Other Service NPCs
Other than hired Service NPCs, there are also some Service NPCs who come on some occasions.
 * Social workers: A social worker come when any babies, toddlers, or children are left unattended for a period, have critical needs, or become too cold or too hot, and will take them away. They also come when a family adopts a child.
 * Repo-men: If bills are left unpaid for 3 days, a repo-man will come to take away some of a family's objects to cover the bill.
 * Mail carriers: Every Tuesday and Thursday, a mail carrier will come to a Sim's house to deliver bills. (In college sub-neighborhoods, the mail carrier comes every 3 days.) Mail carriers also come to take paid bills. Unlike most NPCs in The Sims 2, the mail carrier arrives on foot instead of in a vehicle.
 * Newspaper deliverers: Often called "Newsie." They deliver the newspaper every morning, and also deliver hobby magazines. They are always teenagers. Unlike most NPCs in The Sims 2, they arrive on foot instead of in a vehicle.
 * Carpool drivers: Carpool drivers are the ones who drive the carpool and school bus, fly the helicopter, etc.
 * Pizza deliverers: They deliver pizza when a Sim orders one.
 * Chinese food deliverers: Just like pizza deliverers, only they deliver Chinese food.
 * Delivery people: They deliver most of the things, other than bills, newspaper, pizza, and Chinese food. In the base game, they deliver groceries. They also bring novels (when a Sim finishes one), photo albums, and photo snapshots.
 * Bellhops : Bellhops appear on hotel lots, and will be at the podium in the hotel lobby. Players can click on a them to have Sims check in and check out. They also deliver room service to the Sims' room.
 * Housekeepers: Housekeepers clean the messes Sims make and fix broken things in their hotel room. They arrive in the hotel in the morning and leave at night. Sims can keep them away by putting "Do not disturb" on the door.

Community Service NPCs
Community Service NPCs are Service NPCs who serve Sims on community lots.
 * Cashiers: Cashiers are always teens. Whenever there's a cash register on an unowned community lot, they will occupy it. Although they appear to be very skilled in cashiering, if Open for Business is installed, they may not have a talent badge in operating a cash register.
 * Cafeteria chefs: They work in dorms or community lots in college sub-neighborhoods, if a ShinyTyme Cooktop is present. They arrive at 4 am, and leave at midnight. On community lots, they arrive shortly after the playable Sims do, as long as there is time for them to reach the ShinyTyme Cooktop and prepare food. They will clean up empty or abandoned plates, but only in the room the ShinyTyme Cooktop is in. In dorms, they will occasionally go off-duty without cleaning up empty plates and uneaten food. They will not clean up puddles left by a sprinkler.
 * Baristas: They serve Sims at espresso bars on community lots. They are similar to Bartenders.
 * Hosts: In restaurants, hosts greet Sims at in the podium, and seat them at any available table or bar.
 * Servers: Servers are the waiters or waitresses in a restaurant. They wait on Sims, bring their food, and clean tables and dirty floors.
 * Cooks: Cooks prepare the dishes in restaurants. Unlike other Service NPCs, they cannot be interacted with.
 * DJs: If there's a DJ booth on a community lot, a DJ will operate it. Playable Sims can also work for a while as a DJ and earn simoleons.
 * Stylists: When there's a vacant salon chair in an un-owned community lot, one of these Sims will take over the salon chair, and will be able to give Sims makeovers. They may not have talent badges in Cosmetology. Stylists don't have a fixed uniform, so they can't be distinguished from townies, should they appear anywhere outside an un-owned community lot.
 * Masseuses: If there's a massage table on a community lot, a masseuse will use it. Sims can purchase a massage from them, and they will gain comfort and energy needs. Special massages can be purchased or learned in every vacation destination.
 * Local chefs : Local chefs cook food for Sims whenever there is a food stand on a community lot. There are four kinds of local chefs: Mountain, Far East, Tropical, and Diner. The type of local chef as well as the food prepared depends on the food stand:
 * Flippin' Fred's Flapjack Shack: char-broiled catfish, chicken pot pie, flapjack.
 * Nutritious Noodles Food Stand: chirashi, ramen, steamed rice bowl.
 * Taste of the Tropics Food Stand: luau ribs, pineapple surprise, teriyaki mahi-mahi.
 * One Complete Diner: hot dog, hamburger, gyro.
 * Fire dancers : If there's a fire dance mat on a community lot, there will be a fire dancer. Sims can watch them fire dancing or study fire dancing from them. They are mainly available in Twikkii Island, but they can be available anywhere as long as a fire dance mat is on the lot.
 * Tour guides : Tour guides appear in every community lot and hotel lot in any vacation destination. Sims can book tours from them, and when they do, a vehicle immediately arrives to pick them up.
 * Human statues : When Poised Podium by Performance Arts is placed on a community lot, a human statue will appear there. Sims can watch them or give them tips.
 * Break dancers : If there's a break dance mat on a community lot, there will be a break dancer. Sims can watch them break dancing or study break dancing from them. They are similar to fire dancers.

Wandering NPCs
These NPCs usually wander around the town, or even walk by Sims' houses.
 * Professors: Professors are elder or adult Sims that young adults meet when they go to their first class in a college major. Each major has two professors, one male, one female. They can be interacted with normally, but college students can gain class performance by building relationships with the professors in their major. Playable students can also ask the professors in their major for tutoring, but that decision must be made by the player. Some professors will randomly visit college residential lots, whether or not any of the students living there are in their major. Professors may appear on community lots outside of the college sub-neighborhood, and sometimes appear on secret hobby lots. Sims can also fall in love with a professor.
 * Coaches: Coaches sometimes appear on a lot, whether it's a college community lot, dorm, Greek house, or even a private rental house. They will yell at Sims and try to force them to work out, but can often be avoided.
 * University mascots: There are two types of mascots. One is the llama mascot, who appears to be a costumed male version of the cheerleader. The other is the evil mascot, who is dressed as a cow. They may appear on any lot in a college sub-neighborhood. The llama mascots will autonomously do the school cheer in front of any Sims. The evil mascots will do pranks, will irritate and annoy Sims, and may even do some flirting. When the llama and cow mascots see each other, they will fight. The llama mascots will always win because their Body skill is maxed, while the cow mascots have little or no body skill. The llama mascots have varied personalities, while the cow mascots only have full outgoing and playful points, and are completely lazy, sloppy and mean.
 * Cheerleaders: Cheerleaders are similar to llama mascots, except that they are always female and do not wear full-body costumes.
 * Streakers: Streakers streak in any lot in a college sub-neighborhood. Other Sims will be shocked when they see the nude streakers. They can be interacted with, but they usually don't stay on the lot for very long.
 * Mrs. Crumplebottom : This cranky, strict old woman can be seen in any community lot in Downtown. Mrs. Crumplebottom hates to see two Sims are doing romantic social interactions in public. When she sees any, she will beat them with her purse. She will ruin any dream date, making it into a bad one. She will also lecture any Sims who are wearing undies or swimsuits, or are naked. Mrs. Crumplebottom cannot be interacted with in the usual way and will lecture anyone attempting to talk to her.
 * Dateable slobs: These slobs are very lazy and sloppy, and have the Pleasure aspiration. They can only be found in Downtown or on hobby lots. Slobs are easy to recognize since they wear very dirty clothes, and tend to fart or burp occasionally.
 * Mr. Big & The Diva: Mr. Big and The Diva have different (randomly generated) names in each neighborhood, but they always have the same appearance. Mr. Big wears a red lounge suit and has neat hairstyle, while The Diva wears black dress with red scarf, and has long hair. They are Downtownies and very rich, but also not very nice. If they move into a family, they will add §70,000 to the family funds. They always are at the top of the Slacker career, as Professional Party Guests.
 * Grand vampires: They are the leaders of the vampires in Downtown, and can only be found in Downtown at night. Grand vampires have a bluish skin tone, red eyes, and fangs. They have the pleasure aspiration. Grand Vampires always have the prefix "Count" in their name if male and "Contessa" if female. If playable Sims makes friends with them, they can bite those Sims and turn them into vampires.
 * Wolves: Wolves are a unique breed of large dog, but are slightly different from dogs. Wolves may wander around a lot, and can be summoned by a werewolf.
 * Pack leaders: Pack leaders appears as wolves with black fur and glowing yellow eyes. If a Sim makes friends with them, they can nibble that Sim, and he or she will become a werewolf. They mostly appear at night. They can be greeted and interacted with, but they usually break things and make messes. They also can't be taught any commands or be given commands. Pack Leaders have their own names.
 * Stinky Skunk : Stinky Skunk wanders around residential lots. Sims may pet him, watch him, or chase him off, though the former two actions will cause him to spray them. If sprayed, Sims will get a negative memory, have an empty hygiene bar, and will be a subject of gossip. Pets can also be sprayed. Stinky Skunk is actually based on a cat, and is a universal NPC - making it playable will damage the game files.
 * Penguin : Penguins may appear at a house if it's snowing, there's a snowman in the lot (Whether finished, unfinished, or broken), or a fish is mounted on the wall. He will talk to the snowman for hours and leave. Sims can pet him or shoo him. If he's unhappy, he will leave the house or may eventually pee himself.
 * Unsavory Charlatan : He appears in all community lots frequently. He is a pickpocket, and cannot be interacted with. He may autonomously greet any Sims, and may eventually pick their pocket. Sims with high logic skill may prevent it. If the Sims became his victim, they can attack him or report it to police using the phone.
 * Ninjas : Ninjas only appear randomly in Far East Vacation Destination Community Lot. Sims can learn to teleport by answering a questions from Ninjas, much like Chance Cards. Ninjas always teleport here and there in a lot, and then disappear, so it's quite hard to approach them.
 * High witches: There are two high witches, good and evil. Sims who make friends with one can ask to be turned into a witch. They appear on every community lot, including those in college sub-neighborhoods. The good witch will cast Beautificus Locus and summon a good spectral cat when arriving in a lot, while the evil witch will cast Corruptus Locus and summon an evil spectral cat. When both Witches appear at the same time, they will usually fight each other. The high good witch has full nice points, while the high evil witch has none.

Special NPCs
Special NPCs come when a special or rare occasion occurs.
 * The Grim Reaper: The Grim Reaper only appears when there's a dead Sim on a lot. Most of the time, Sims can plead with the Grim Reaper to bring the dead Sim back to life, unless they died of old age, drowning, or have been eaten by Cowplant. When a Sim dies of old age happily, The Grim Reaper will appear with 2 Hula Zombies accompanying him.
 * Hula Zombies: Hula Zombies appear only when a Sim dies of old age. They will dance hula while The Grim Reaper escorts the dead Sim. Their face resembles Bella Goth a lot.
