|Jimmy falls into a world of fantasy and magic, as he and his cousin Len battle the forces of evil. But does Jimmy realize what he's gotten himself into?
The entire show is a goof, really, because Dungeons and Dragons and other such role-playing games that this episode is targeting do not operate even remotely like how the show portrays it. None of actions depicted in "Castles and Cauldrons" have any authentic similarity to table-top role-playing games of any kind.
The name of this episode is a reference to the real-life game "Dungeons and Dragons."
