ZOOB Inventors" Kit exhibits builders and their creativity, boasting the winners from our previous Inventors" Contest and featuring their creations along with the stories behind them. The kit comes with 100 ZOOB pieces to re-create the award winning designs, or to build your own. ZOOB is not like any other building set - the pieces include gears, axels and joints that snap, click, and pop together! With rotating, spinning and extendable parts you can actually design a toy to play with, instead of just building something to look at. Create monsters—or vehicles—or monsters that turn into vehicles! The possibilities are as endless as your imagination! Recommended for children 6 years of age and older.
