Terror of the Black Knight
Billy and Irwin are building a go-kart for a race in, what is presumably Billy's basement, when Mandy opens the door to the basement. Billy and Irwin laugh about how Mandy and Grim can't participate, because they are a girl and a skeleton, respectively.
Later, the race is about to begin. The competitors include: Sperg, Mindy, a tag team of Billy and Irwin, and Mandy. Strangely enough, Grim is Mandy's go-kart. There is also a "mystery contestant" (wearing a paper bag over his head) in a little red wagon. The entire crowd laughs at said mystery contestant. The race begins. Mandy and Mindy are neck-and-neck, but Sperg is busy ordering a cheeseburger, but when Sperg sees Billy and Irwin. He decides to get serious. He chases after Billy & Irwin, who pass by Mandy and Mindy. Mindy's car eventually becomes stuck in traffic, and Sperg causes Mandy and Grim to nearly fall off the suspended highway. Sperg destroys Billy and Irwin's go-kart, and Sperg is close to the finish line, but Grim uses his scythe to open a whole in the ground, which Sperg falls into. Grim is about to win, when the hole opens up again, propelling Grim, Mandy, and Sperg into the air. The mystery contestant crosses the finish line first. Mandy unmasks the mystery contestant, who turns out to be Pud'n. Everyone laughs at him once again.
