Prank

Pranks are an interaction where one Sim uses physical humor to amuse— or annoy — another Sim, or an interaction involving objects. They were first introduced under that name in The Sims 2: University, though some of the abilities Sims could gain from Crystal Clear Ability Rocks in The Sims: Makin' Magic are essentially pranks.

Pranks have been re-introduced, but are in a different form, in The Sims 3: Generations expansion pack. They are also included with The Sims 4 base game.

The Sims 2
The Sims 2: University introduced three new pranks that one Sim can pull on another. With the new addition of rugs from The Sims 2: Nightlife, children can do a static charge prank. PlantSims have a special prank. While the prank is taking place, other sims in the room will gather around to watch it. Playful sims will laugh and Nice sims will watch worriedly. Sims with low playful and nice scores may boo the prankster.


 * Ventrilo-Fart - The prankster will break wind and blame it on the victim, causing major humiliation if in a public place.
 * Joy Buzzer - The prankster will shake hands with the victim, and "electrocute" them with a joy buzzer. This is completely harmless to the victim.
 * Water Balloon - The prankster distracts the victim, and then quickly whips a water balloon at their head. A puddle will form nearby.
 * Static Charge - Requires a rug, and can only be done by kids. The prankster must be standing on a rug first before the option will appear. The sim will generate static electricity from the rugs and shock the victim. The shock is not lethal.
 * Pollen Cloud - This prank is unique to PlantSims. The PlantSim will blow a cloud of pollen into the victim's face.

Pranks can have a positive or negative effect on two Sims' relationships, depending on how high it is. For example, if a Sim's good friend pulls a prank on them, the outcome will have a positive effect on their relationship. When a Sim's enemy pulls a prank on them, it will have a negative effect on their relationship. The same counts for acquaintances - the higher the relationship, the higher the chance of a positive effect.

There are also pranks which involve objects.


 * Fire sprinkler prank - The prankster will take out a lighter and put it under a sprinkler, causing it to go off. All sims in the room will react negatively to the sprinklers, and a watery mess will be left behind.


 * Soap in fountain prank - The prankster will take out a box of soap and pour some into the fountain, which will cause bubbles to form. Other sims on the lot will go over to look at the suds, and may either laugh or look disapprovingly, depending on their personality.

The Sims 3
There are no pranks in The Sims 3 base game, however The Sims 3: Generations adds a pranks system for teenagers. An early game trailer showed a number of pranks, including a Sim lighting off a "stink bomb" in a library. Sims can be punished if they are caught preparing a prank, which will result in the police taking them home. Sims will then be grounded by their parents. Only children and teens can pull pranks. Children can plant booby traps, and teenagers can also prank neighbors and their school. Sims will get a negative moodlet if they get pranked, unless they have a good sense of humor.
