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.
