A Beavecoon. A beavecoon is (in the words of Spencer's deluded imagination) a creature "yay long, yay wide, head of a beaver, rump of a raccoon." In iBelieve in Bigfoot, Spencer tries to find the beavecoon while Carly tries to find Bigfoot.
Is a Beavcoon a real animal?
"It's a mix between a Beaver and a Raccoon."
