The hairy bus first appears during the scene where Carl uses meatwad to steal parts from cars. After stealing the bus' intestine, the bus appears near Carl's house later. The seninent Hairy Bus blackmails Carl to give him a new colon in exchange for not revealing footage of Carl stealing car parts the bus recorded. The bus instructs them to get the new colon from his brother "The Flesh Train", who is much nicer than The hairy bus. After Carl takes his colon, he shows the Hairy bus, but Frylock blows up the bus using the tailpipe and a stick of dynamite.
