The ZOOB Mobile Mini 4-Wheeler is a fantastic starter set and a great companion to ZOOB collections that need wheels. This set includes 12 ZOOB pieces, wheels that double as gears, and an instruction guide for vehicles such as a Dune Buggy, a 3-Wheeler, and a Mini Pace Car. 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! ZOOBMobile puts wheels on your creations to make your ZOOB go ZOOM! Recommended for children 6 years of age and older.
