Vincent Shadow isn't particularly good at sports - he doesn't have a lot of friends and he is constantly being picked on by his classmates at Central Middle School. But it is Vincent's unusually creative mastermind that truly separates him from other kids his age. With his top-secret attic lab full of tried and tested (and often failed) toy prototypes - from Liquid Superballs to Bullz-I Basketballs and Sonic Snorkelz - and an off-limits sketchbook packed with all of his creative ideas, the toy invention possibilities are endless. 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 realises that playtime is over: it's time to get serious about toys.
