Scooby-Doo and the Mystery Inc. gang pick up a hitchhiking Gary Coleman, and the Mystery Machine soon proceeds to break down multiple times, finally leaving them stranded at a haunted castle owned by David Cross. The show contained multiple references and gags that take jabs at the original show, musical numbers by Big Bad Voodoo Daddy, and concluded with a nonsensical ending, with Coleman pointing out all of the plot holes in the story. Scooby interrupts him by licking his face until the episode ends.
