Just when you re sure Wally has bungled through every misadventure imaginable this nerdy kid stumbles staggers and k-splats his way smack dab into a brand new frontier - the human body. When he and Wall Street his best friend (even if she is a girl) visit a local laboratory they are accidentally miniaturized and swallowed by some unknown stranger. It is a race against the clock (let alone Wally s own klutzoidness) as they fly through various parts of the body - from the stomach to the blood system to the brain to the eye - in a desperate search for a way out while all the time learning how fearfully and wonderfully we are made.
