From Barney Bunch wiki
Drew Pickles believe it or not. It all started when Drew and The Barney Bunch went to a Mardi Gras and and went into a sex shop and bought some anal beads. He was created when Drew was raped my Captain Pollution from Captain Planet. Drew had him in his ass and Drew thought he had to take a volcanic shit and he fished him out. Drew would also fart in his mouth as a treat and would feed him garbage like used condoms.
