""Boffin Boy and Wu Pee are travelling through the desert, looking for the lost city of Tickle-my-tum. The trouble is, they're not on their own! Their old enemy Red Wolf is in the city too, and he's looking for lost treasure. Actually, Red Wolf is not really Boffin Boy's biggest problem. A Death Worm thingy is in the city too, and it wants to keep its treasure for itself."--Back cover.
