It started with a bump. Grandad's false teeth (made from super-lightweight Jupiter gold for the gummy bit and mega-diamonds from a titchy little planet near the Dog Star for the teeth) slipped out of his fingers, shot out of the meteor's bathroom window and hurtled across space. Kip, Mum, Baby Kissy and Spotty jumped into the flying saucer and chased the teeth all the way to the North bit of Earth. But - CLUNK, CLUNK, CLUNK - the old saucer broke down as it bumped and thumped its way through the atmosphere, skidding to a halt at the bottom of a mountain. As Mum sets about fixing it Kip, armed with the old mobile radio tracker and his kit-bag full of essential supplies, sets off to find Grandad's teeth. Does he meet anyone who can help him? And can he find the teeth before anyone else gets their hands on them?
