Squirrels

The squirrels are a group of squirrels who live in the park. They can talk and are about as smart as humans (although you'll occasionally get one who's smarter or less smart than the average human) due to some pills that Thaddeus Euphemism fed them. They have their own currency (acorns) and are often seen scheming, usually to make money. For example, one of them did the "Nigerian prince" scam and in one story arc, a bunch of them took over Clones 'R' Us. Despite being sapient and able to talk, they still live outdoors and have a squirrel's physiology and interests, and they're hardly ever seen wearing clothes, although a few have worn clothes on occasion.

Trivia

 * Several have been named, including Carl and the late Doug.
 * Their lawyer is a bear who's also taken the pills.
