ZOOB 35 Piece Building Set contains brightly colored pieces and 2 instruction guides to make over 20 creations like the Sxorpion or the ZOOBdude (or create 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.
