Les Squirrels are a family of squirrels that act as a mafia. Their names, language, and accents are French. They wield wooden guns with rubber bands attached, slingshots, and use acorns either as projectiles or ammo.
Considerably, as Randl is merely a grump, and Princess is a spoiled brat but otherwise tends to get along with the other kids. The squirrels are the only recurring characters that could be considered the shows' "Villains"
While their debut in an actual episode is "The Spitting Tree" they actually first appear in the theme intro, as background cameos while Harvey, Fee and Foo walk across a branch.
