An often shy, comforting creature that lurks around campsites. They forage for food, especially brownies or peanutbutter whilst campers are away from their tents. A Monkeybutt is a carefree, yet hyper animal who enjoys climbing tree's and often has a naughty side flashing their butt's to attract female attention. A Monkeybutt is rare creature, but enjoys attention of sorts and will be your friend for life.
