Mummies Alive! (1997)

Season 1: Episode 29

The Monster Truck Rally of the Century is taking place, and Bubba Baxter, Presley's race-truck driver friend is entered. Bubba accidentally gets knocked out, so the Mummies and Presley drive the unconscious Bubba's truck in the race for him. Meanwhile, Geb - the mighty Spirit of the Earth - wants to take his mud bath in peace, but he is right in the path of the race. The mud makes inanimate objects come to life, so the trucks in the race change into Monster Trucks. These include a bear, a horse, a lion, a skull, and Bubba's truck becomes a shark.
