Mascot

Mascots are costumed NPCs who appear in The Sims: Vacation and ''The Sims 2: University

Vacation mascots
Vacation mascots appear on Vacation Island lots and interact with children. Unlike the other Vacation NPCs, mascots arrive in the morning and leave at night. Each area of Vacation Island has its own mascot. The snowy mountain area has Betty Yeti, the forest area has Archie Archer, and the beach area has Marky Sharky. The only difference between these three characters is the costume.

Mascots will follow kids around and try to get their attention, often with little regard to whatever the kid may be doing at the time. Mascots will often want to hug kids, but a kid who is in a bad mood may respond by hitting or kicking the mascot.

University mascots
There are two types of costumed university 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. The cow has few, if any, body points, while the llama mascot has the body skill maxed out. If both of these mascots appear on the lot, they will more than likely get into a fight.

There are three of each, and it appears that each college lot is assigned its own llama mascot and evil mascot. However, this is not obvious, as mascots are rarely seen out of costume.

Like other college townies, mascots are always freshmen.

A mascot can be controllable when added into a household, however the game will generate a new one.

The evil mascot
Unlike the llama mascots, who are always male, an evil mascot can be either male or female. He or she will come into a dorm, house, or Greek house and pull pranks, fight with, flirt with or otherwise generally annoy their Sims. One of the two ways an evil mascot can wreak the most havoc is by setting off a sprinkler, which makes a large mess, which will have to be cleaned up. The other way is by flirting with a Sim while the Sim they are in love with/engaged to is watching. This will cause the other Sim to become furious at their significant other and effectively destroy the relationship. (This can be extremely frustrating and the best way to reverse this is by cheating.) They also like to call Sims all the time to bother them, even after they graduate.

An evil mascot may have some points in the Body skill, but both the llama mascots and the cheerleaders have the Body skill maximized. So, when evil mascots get into fights with llama mascots or cheerleaders, they lose.

If Open for Business is installed, and a SentryBot is present, it will shock the evil mascot.

An evil mascot who is added into a household can perform the school cheer and have special clothing like the llama mascots.
