The goblinz have built a go-kart - the GobbleKart - and are taking up to Gaspup Hill to try it out. Unfortunately Old Ma Musty, the witch, lives on the top of the hill, and her goat Bill has escaped. The goblins think it would be a good idea to hitch the goat to the cart, just as Old Ma Musty sends out a searching spell - oh dear! The witch is furious and the kart and the goblinz end up in the pond.
