Vincent Shadow isn't particularly good at sports and is constantly being picked on by his classmates at Central Middle School. But it is Vincent's unusually creative mind that truly separates him from other kids his age.

Vincent's top secret attic lab is crammed with toy prototypes --from Liquid Superballs to Bullz-I Basketballs and Sonic Snorkelz--and he has a sketch book filled with drawings of toys he still wants to build. So when a chance encounter with an eccentric toy inventor offers him the opportunity to go from unknown weird kid to toy inventor extraordinaire, Vincent realizes that playtime is over: it's time to get serious about toys.
