Courage the Cowardly Dog - Season 4 Episode 12

"Cabaret Courage" The Family is sightseeing in Hollowood, California, when a manhole opens beneath their feet. They plummet down a series of long, intestine-like tubes and land in an underground cabaret, in what appears to be a stomach. A homunculus, embedded in the wall of the stomach, offers the Family great prizes if they perform for him. The Farmer and Muriel eagerly accept the opportunity, but end up being thrown into an intestinal pit to be digested, because they performed not for genuine feeling and generosity but for personal and material gain. Courage, however, turns down the offer of glitzy, expensive gifts. He'll perform in exchange for the Family's freedom. Courage must rescue Muriel and the Farmer before they are digested. "Wrath of the Librarian" While digging up "treasures" he'd buried in the yard, Courage finds a library book that is two years overdue. He takes it back and learns he owes several thousand dollars in overdue fees. He returns home with the book, unsure of what he will do. Muriel and the Farmer both touch the book and get paper cuts from it – and they transform into characters from the book. Courage must find a way to change them back AND pay off his library debt (which grows by the minute).
