List of Easter eggs in The Sims

An Easter egg is a message hidden in the object code of a program, movie, book, CD, DVD, or video game as a joke, intended to be found by persons disassembling or browsing the code.

There are many Easter eggs in The Sims series. Some of these are hidden in the actual game play and others are hidden in the code.

The Sims

 * The Yeti from the Vacation expansion pack appears on the TV screen if the cartoons channel is selected. If Superstar is installed, a Betty Yeti film-poster is added to the game.
 * In the neighborhood screen, the Loch Ness Monster occasionally appears in the water for a few seconds. The monster also appears in Downtown and Vacation Island.
 * There are several references to the game's creator, Will Wright, including the doll house and the "Whack-A-Will" game from the Sims Vacation.
 * The baby doll souvenir from The Sims Vacation bears a striking resemblence to the default look of babies in The Sims 2.
 * The "rosebud" cheat might be a reference to the movie "Citizen Kane."
 * If there is a Christmas tree, fireplace, and a table with cookies in the same room late at night, Santa Claus will come, and leave the family a present.
 * There are some real people starring in The Sims, for example Drew Carey, Marilyn Monroe, Andy Warhol, Avril Lavigne, and Christina Aguilera.
 * A highway was named after Gunther Goth; it is called the Gunther Goth Highway.
 * There are many Easter eggs with the Crumplebottom family such as the court house next to the Goth Sr home, the prune tree, and the park.
 * On the starting screen, highlight the Maxis logo and click it. A cartoon of Will Wright with Sims crawling all over him will appear.

The Sims 2

 * Bella Goth: There are many references to this mysterious Sim in the game. Bella Goth appears on the milk cartons and newspapers in the game. It is rumored that Bella and her brother Michael are standing in the hot air balloon neighborhood object in the game; others suppose this is the Dreamboat and Blonde Bombshell townie characters from The Sims: Hot Date expansion pack. Bella appears in many of the decorative photographs of the game, one being a picture of herself named "Bella Squared". She is also a townie in Strangetown. With the Apartment Life expansion, the neighborhood has a statue of Bella holding a PlumbBob. In The Sims 2 for PlayStation 2, the name of a refrigerator is "Chow Bella Bachelor".
 * Onomatology: Several pre-made Sims in the game have names that allude to a meaning. For example, Olive Specter's ghosts, Rigger Mortis and Earl E. DeMise.
 * Hidden Painting: There is a painting hidden within the games files that depicts an 18th century couple. The female in the painting closely resembles Glenda the Ghost (an NPC ghost from The Sims Makin' Magic), though the identity of the male is not known.
 * The Pleasant Family on TV: The Pleasant family appears in one of the clips in Sims Broadcasting Network. One of the clips are the Pleasant sisters fighting and the pizza commercial.
 * Freezer Bunny: One of the most common Easter Egg in The Sims 2. It represents a pink bunny cartoon and first appearing on the back of a juice carton in the community lot freezers.
 * Simpsons House: A house on the train table in FreeTime bears a striking resemblance to 742 Evergreen Terrace, the house of the Simpsons family.
 * The Flying Pig: A neighborhood object released with The Sims 2: Open for Business. Appears in neighborhoods with a water tower. It also appears as a decoration on a tree in the FreeTime train table.
 * The Spaceship: A neighborhood object/event released with Pets. When a crashed spaceship is placed in the neighborhood, a spaceship arrives with a searchlight to find the crashed ship.
 * The Spaceship's Number Plate: Says 'anm8er' (It sounds like "animator"). When an abduction occurs on the lot and the UFO comes to return the Sim, the number plate can be seen.
 * Grim Reaper's Bio: When using the  cheat to view the Grim Reaper's bio, it says that his favorite band is Styx.
 * Hidden Lot in Belladonna Cove: There's a hidden lot at the edge of Belladonna Cove, called Watervista Palace. It can only be seen by using the cameraman mode (Tab). It resembles a lot like Baba Yaga's hut.
 * Tree Ring: Player can read many trivial information from the Tree Ring from Bon Voyage. One of the trivia is a reference to all of Don Lothario's lovers; DL+CG, DL+DC, DL+NC, and DL+KL.
 * Career Reward: The Sims 2 logo can be seen on the lower part on the 3rd mat of the Medicine career reward.
 * Maxis Outfit for Girls: In The Sims 2, there is an outfit for girls with Will Wright on front and a Maxis logo on the back.
 * Veronaville Residents' Gender Preference: Using SimPE or another third party editing program to open the character files of several pre-made male Sims in Veronaville (e.g. Kent Capp, Cornwall Capp, Patrizio Monty etc.) reveals that they have a slight gender preference for males at the beginning of the game, despite the fact that they are involved in heterosexual romantic storyline. This is possibly a reference to the ongoing critical debate over the possible sexuality of William Shakespeare, on whose life and plays the neighborhood is based. It could also be referring to the fact that, in Shakespeare's day, only men were allowed to act.
 * Hot Dog Stand Counter: On the counter of the hot dog stand in Apartment Life, players can see some recognizable pictures. The pictures include the photos from the photo album of the Smith family, the Grunt family, the Lothario family, the Broke family, and many more. There are also the pictures of Romeo Monty and Bella Goth.
 * Noticeboard: On one of the noticeboards from University, if the graphic quality is set to high, players can read a pinned paper with words written in alphabet "OPEN" and mirrored "HOUSE".
 * Phone Book Cover: The phone book children use when playing chess contains a cover with alphabet on it, despite the fact there's also Simlish on it. It says a series of "asdfsf dfasd asdf." It can be implied that the developer only added random letters while designing the phone book.
 * Video Game: A preview of The Sims 3 in its beta version appears as a video game that is shipped with FreeTime.
 * Sir Bricks-a-Lot: One of the toys that can be crafted in Open for Business is Sir Bricks-a-Lot. This is a play on Sir Mix-a-Lot, who is an African-American rapper/songwriter. Of the designs available for the toy, there is one that has a beard/stubble, meant to look like the real-life singer. Additionally, Sir Bricks-a-Lot reappears in The Sims 3: Pets.
 * Chance Cards: The chance card for the Master of Ceremonies position in the Entertainment career track refers to The Simmy Award from The Sims: Superstar.
 * Wall Lamp: One of the wall lamps is called "Prisoner of Azkalamp". This is a reference to Harry Potter and the Prisoner of Azkaban, the third novel in the Harry Potter series by J.K. Rowling.
 * Floor Lamp: There is a floor lamp called "Rave Against the Machine", a reference to popular American rock band Rage Against the Machine.
 * End Table: There is an end table called 'Crazy 8' this could be a reference to the 'crazy 88 gang' from the film Kill Bill vol. 1.
 * Whistling: Sims with enough Music and Dance enthusiasm will occasionally whistle a segment of the buy mode song from The Sims.

The Urbz: Sims in the City

 * When starting The Urbz: Sims in the City, if the player does not press start at the title screen, the game will play a demo. This does not occur in the PS2 version.
 * Also on Xbox, if the player loads a game in The Urbz: Sims in the City and plays any Urb or goes to a different location, pictures will sometimes be seen.
 * In the GameCube version of The Urbz, when going to Blankwood Towers, the player can see a dresser that looks like a Nintendo GameCube which allows Urbz to dress as Darius or Roxanna Moxie.
 * In Kicktail Park, if the player shakes the Ice Cream Machine while he/she is in a bad mood, the hands of a monkey will shake the Urb and kill him/her.
 * There is a special Urb called Bobo. He does not appear in the relationship list (But he is listed on the Call Urb screen) but he can be made to join your crew in which the player can control him. Although he has Central Station clothes, he is treated as a Gasoline Row Urb.

The Sims 2 (console)

 * In The Sims 2 for console, when looking at the Comic objects, one can see Darius from The Urbz: Sims in the City.
 * Objects and Sim animations in The Sims 2 for console are the same as The Urbz: Sims in the City, this also occurs on The Sims 2 Pets.
 * When using a metal detector, a Sim can find a copy of The Urbz: Sims in the City.
 * In the GBA version, when starting the first episode, Daddy Bigbucks will mention that there are gangster buddies back in Miniopolis though no known gangs have appeared in The Urbz: Sims in the City.
 * In the PSP version, Bella's secret's will mention that she never loved Mortimer, and instead married him for his money.
 * In The Sims 2 for GBA, Daddy Bigbucks mentions the Goth family and it can be seen when starting a new episode or when finishing it.

The Sims 2 Pets (PSP)

 * When going to Town Square, players may get the message "Today is the Cat Day!". Oddly, this may also appear in The Sims Castaway at random times when looking inside a bottle.

Sims

 * Several of the easter eggs involve the Tragic Clown - first seen in The Sims. His picture appears at the back of the milk carton, replacing Bella Goth. A parody fish has the name the Tragic Clownfish. Tragic Clown's existence is shown in his grave in Pleasant Rest Graveyard.
 * Vincent Skullfinder, from MySims, is a deceased Sim buried in Pleasant Rest Graveyard.
 * The Goth family is incomplete. There is a Sim in Goth's graveyard named Lolita Goth. Some players believed that she is Gunther's sister, in replacement of Frida Goth, because Frida didn't appear in The Sims 3 yet, only until she reappeared in Supernatural. Some players believe that Lolita is Gunther's ex-wife. For theories, see Lolita Goth/theories.
 * In Late Night, there is a possibility that Sims will exclaim, "This place is hotter than Hank Goddard that one time he caught on fire!" when visiting a random hotspot. It is also possible they will exclaim "This place is as hot as Connor Frio with a bad case of hypothermia".
 * There is a secret cave on the outskirts of Sunset Valley and Riverview, and inside a log in Appaloosa Plains. By taking a closer look, the player will be able to see two glowing "monster" eyes. The mine is only a neighborhood decoration. There are also many rare minerals close to the abandoned mine.
 * In Twinbrook near the house called "Swampy", there is a fake jackalope with a wooden back and a wooden stand holding it up.
 * The game's main theme is a remix of The Sims 2: University theme.

 * One of the game tips states that "If all Sims ever created joined hands in a chain, they would stretch from Sunset Valley to Bridgeport and back over one billion times!"
 * The toy train set that's included in Supernatural resembles a small version of Sunset Valley, with the city hall, the theatre, the stadium, the spa, the supermarket, the bookstore, the hospital, the central park and the lighthouse.

 * In The Sims 3: Late Night, the fountain in the center of Bridgeport resembles the picture from the loner trait in Map View.
 * In The Sims 3: Generations, there is a dog paw on the baby gnome shirt. It could be a hint to the next expansion pack, which was The Sims 3: Pets.
 * When children or teens have a school trip to the graveyard mausoleum, they may receive a painting. The painting has a figure of a ghost with a green color and what appears to be a black coloration in his stomach just to the left of the mausoleum. It is speculated that this reveals a new type of death in an upcoming expansion pack, and that it is most likely a ghost Sim who died of illness as featured in The Sims 2. It was rumored that this type of death will be shipped in The Sims 3: Seasons, but it didn't. It was later revealed that the ghost is a new form of death, death by magic, as shown Supernatural trailer.
 * In The Sims 3: Pets, there is a painting called "Rainbows! Lasers! Cat!" which is a possible reference to the popular internet meme, Nyan Cat.

 * There is a bookshelf in the base game that has a few pictures. One of them shows a picture of either Bella Goth or the young woman on the front of The Sims 2 box. Another picture is clearly of the dog on the front of The Sims 2: Pets box.

Objects

 * The Access Aperture Door (available after purchasing Lunar Lakes), could possibly be a nod towards Valve's Aperture Science Facility shown in both Portal games, yet the word is also used to describe an opening which allows light to enter; possibly meaning a fancier word for door.


 * The Lucky Door is said to be made by Mr McMann from Pleasantview after he won in Bingo seven days in a row.


 * There is another door called Mags' Door, the door is in the style of the 50s and it might be a reference to Mags Newbie.
 * Freezer Bunny is back! He appears in the Freezer Bunny arcade game, and as a statue. He also appears on top of the candy fountain on the cover, occasionally inside the washing machine and on the fountain inside the game in Katy Perry's Sweet Treats.

 * A telescope that comes with Outdoor Living Stuff mentions Morrigan Hemlock who is a playable character who lives in Bridgeport.


 * There is an archway that is a direct reference to "Stairway to Heaven" by Led Zeppelin. It comes with the base game and is called the "Archway to Heaven". Its description is "There's an archway that knows, if you're wealthy with gold, then you're buying an Archway to Heaven". This is a reference to the first few lines of "Stairway to Heaven"; "There's a lady who's sure/All that glitters is gold/And she's buying a Stairway to Heaven".


 * An object that comes with the Pets expansion pack is "Sir Bricks-A-Lot, Jr.", a reference to the rapper Sir Mix-A-Lot, and the original "Sir Bricks-A-Lot" in The Sims 2: Open for Business.


 * A sink named "The Unsinkable Sink" might be a reference to Titanic, as the Titanic used to be called "The Unsinkable Ship".

The Red Faction reference is slightly odd, considering EA had nothing to do with the game; it is published by THQ and designed by Volition.
 * When receiving a certificate for mastering Athleticism, the athletic institute is named "Grodiek Institute", a pun on a creator of the game, G. Rodiek.
 * While it may be just a name, Morrigan Hemlock may also be a reference to Dragon Age: Origins.

The look of the item and a part of its description - "Please note, we'd like to take a moment to remind you that the Comrade Cube cannot, and will not, speak" - are both references to the weighted Companion Cube from Valve's Portal series where GLaDOS constantly reminds the player that the weighted companion cube cannot speak.
 * On the side of the Starlight Shores Rabbithole, you can see a poster that looks a lot like a promotional picture from Battlefield 3.
 * In The Sims 3 there is a street lamp called 'A Street Lamp Named Desire,' a reference to the Tennessee Williams play A Streetcar Named Desire.

 * In Ambitions, when the Sim is investigating a tunnel dug by a miner, sometimes a message will pop up saying "(Sim) saw an officious looking white rabbit running down a tunnel, but decided to leave that business for some other sucker". This is a reference to the book Alice's Adventures in Wonderland by Lewis Carroll.
 * One of the novels your sim can write is Waiting for Godat, an obvious reference to the play Waiting for Godot.
 * One of the houses in Lunar Lakes mentions seeming "bigger on the inside", a possible reference to the TV show Doctor Who. Likewise, the object The Lightning Leap Atomic Molecular Aranger, introduced with The Sims 3: Supernatural, is a reference to the TARDIS from Doctor Who in both its design and functionality.
 * If a teen is crowned as Prom Queen, their moodlet will say "They like me! They really like me!". This is a reference to Sally Field's acceptance speech for her Academy Award for Places in the Heart.

Other

 * Occasionaly airplanes can be seen in the sky.
 * Some of the rabbit holes have music from MySims as their background music.
 * When Travelling to the Past in the Time Machine from Ambitions your Sim may get a message about horse riding which also mentions that it could be useful in near future: that must be a possible hint to Sims 3 Pets.
 * On the big rocks near Crystal Springs in Sunset Valley there are alien carvings on the rocks presenting some sort of message.
 * Pre-made deceased Sims in Twinbrook, Barnacle Bay and Bridgeport are all light-green skinned, grey-haired, barefoot and dressed in similar hues. Also these Sims share their last name with some Twinbrook families, possibly meaning that they may be related to them but oddly they don't appear in tOboroten-the-sims-3-pitomci.jpg?]]heir family tree.
 * One of the background music songs in any grocery stores bears a resemblance to the song from the movie "A Boy Named Charlie Brown" called "Champion Charlie Brown"
 * NPCs from Bridgeport and Barnacle Bay often don't have the typical and appropriate traits to the determinate NPC job, for example babysitters don't have the Family-Oriented trait.
 * As the Easter egg above, if you look at the Big Bling Household in Bridgeport, you can see a description saying that no one knew how these "former Twinbrook residents came under the same roof."
 * In the theater at Bridgeport, there is a movie poster of a doctor examining a woman, as seen on The Sims 3 Ambitions box.
 * The football clips on the sports station are a game between the Pittsburgh Steelers and Jacksonville Jaguars from Madden NFL 10.
 * In CAW it says set "Beautiful Vista" buff instead of moodlet. This may give away The Sims Medieval as moodlets are called buffs.
 * A playable song is named Flamenco Fever, perhaps a reference to the Caliente family.
 * All the T.V. shows are made with The Sims 2 and The Sims Stories.
 * The name of the Twinbrook Stadium is Bachelor Stadium, making a reference to the Bachelor family (perhaps because Michael wishes to be an athlete).
 * The newspaper may say that Twikkii Island is the #1 vacationing island. This a reference to the island that appeared in The Sims 2: Bon Voyage.
 * When travelling to the past, the player may randomly get a message about the disappointment of the Sim that personal teleportation is still not possible 50 years after The Sims 3. This makes no sense, since teleportation does exist in The Sims 2 and The Sims Stories and can be achieved by meditating or learning the Ninja teleportation trick. Kids can also be teleported by the Social worker. Repomen also teleport in The Sims 2 and The Sims Stories if the walls are blocking the objects. Teleportation is also possible through the Teleporter Challenge Reward. Although it's possible the game means an object that allows personal teleportation. Also in World Adventures, Sims can teleport by using Zeneport.
 * One of the songs used when entering the elevator for The Sims 3: Late Night expansion is one of the songs used in build mode in The Sims.
 * The cooking channel plays a song from the The Sims: Unleashed.
 * Some of the songs playing while in the neighborhood view of France are from the neighborhood view of Magic Town in The Sims: Makin' Magic.
 * Under the "Themed" category while designing objects, one pattern shows three real-life sports cars: Audi R8, Chevrolet Camaro, and Lamborghini Gallardo.

 * Inside the school rabbit hole there is a map displayed on the wall that appears to be a reversed map of the United States.

The Sims Medieval

 * When playing a quest as the Wizard, the player may be given the chance to undertake an optional quest objective, "scry into the distant future (just for fun)". A dialogue box appears describing a "beautiful woman in a red dress" and a confused image of "Gothic bells", clearly intended as a vision of Bella Goth.


 * When the music box is opened, two small dancing automatons can be seen inside. The female figure wears a long red dress, which could possibly be a medieval variation on Bella Goth's iconic outfit. Her male dancing partner is also dressed smartly in dark hues, and could possibly be a medieval version of Mortimer.
 * When the Blacksmith is making something, they will get the 'Hammer Tyme' buff, with 'Thy cannot touch this' as the description, a reference to the MC Hammer song.
 * When any hero sim gets a minor wound, the description says, 'Tis merely a flesh wound. I've had worse', a reference to Monty Python and the Holy Grail.
 * There is a townie called 'Rodger the Shrubber', another reference to 'Holy Grail'.
 * When sending a parrot to 'Hunt for Treasure' the description says 'How much treasure can a parrot carry? I suppose it's a question of weight ratios,' another reference to 'Holy Grail'.
 * There is a metal that you can find called "Mithral", which is a possible reference to the Elven metal "Mithril" in the works of J. R. R. Tolkien.
 * There's a song played on the lute called Lament for Mortimer. Likewise, there is a song on the fiddle called Bella in the Lowground.
 * When playing the quest to kill the monarch, the spy discovers that the monarch is an imposter, and the true monarch's bones are buried under the name of Sambert Limnel. This is a reference to Lambert Simnel, who was a 'pretender' in Henry VII's reign. Lambert Simnel pretended to be the Earl of Warwick so as to claim that he was the true heir to the throne. This is practically the opposite to what happens in the game play, therefore it is ironic that they swap the letters around of the first and last names.
 * If Pirates and Nobles is installed, a Sim can become a member of the Pirate faction. If they do this, they can choose the special "Scurvy Strike" while dueling, where they spit in their opponent's eye. If this fails, the Sim gains the buff "Blinded by Spit," with a description of "So you think you can blind me and spit in my eye??" This is likely a reference to the Queen song Bohemian Rhapsody.
 * While asleep, there is a chance a character will get a dream related to a bard named "Andy Island", singing a comical song about "crude lust". This is likely a reference to the comedy band The Lonely Island, and their lead vocalist, Andy Samberg. The options in the opportunity are "The night starts..." and "To the good part!", both phrases used in their song "Jack Sparrow".
 * The chickens in the Merchant character's Market, despite being functionally no more than decorative items and having no interactions available, can occasionally be seen with Relationship plus or minus signs floating over their heads after clucking at each other for a while.

Llamas
The reappearing llama reference is an old joke from Maxis dating all the way back to SimCity 2000, when the speed names were "Pause", "Turtle", "Llama", "Cheetah", "African Swallow". Llamas appear throughout most games of The Sims series.


 * The theme appears as the mascot of the college in The Sims 2: University and various pictures.


 * The pirate ship in Bon Voyage (and Hogan's Deep Sea Diner in Barnacle Bay) has a llama figurehead on it as well as the face of a llama.


 * Mr. Humble´s computer has a picture of a llama on it.


 * Calling to invite over a person who doesn't particularly want to accept said invitation, they will sometimes say "I'm sorry. I can't; I have to feed my pet llama," or "I'd rather play Myshuno with a pack of llamas."
