Evil mascot

The evil mascot is the character in The Sims 2: University who is dressed as a cow. The evil mascot can be either male or female, unlike the llama mascot (who is always male). He or she will come in to your dorm or even your house and pull pranks, fight with, flirt with or otherwise generally annoy your Sims. One of the two ways an evil mascot can wreak the most havoc is if you have a sprinkler, which makes a large mess and your Sim will have to clean it up (or influence another sim to do so). The other way is when the evil mascot flirts with one of your sims while the sim they are in love with/engaged to is watching, causing the other sim to be furious at their significant other and effectively destroying the relationship. (This can be extremely frustrating and the best way to reverse this is by cheating.)

The evil mascot has no points in the Body skill, but the good mascot has the Body skill maximized. When the two mascots are on the same lot at the same time, they tend to fight, and the good mascot always wins the fight.
