Naked Little Dude was sent out by his wife to get the shopping. He found a copy of The Big Book of Wallslides on the way home and got absorbed in it. He also lost the shopping. His wife's response to this is not sympathetic. She sends him on an adventure to retrieve everything that has gone missing. The local wildlife has begun behaving in ways that are difficult to explain. Seven worlds of platforming follow, with enemies to outwit, new skills to discover, and earlier locations worth revisiting for things initially passed over. The humor does not stop.
