ZOOB 125 Piece Kit is a box of 125 brightly-colored pieces to create your own models. ZOOB is not like any other building set – the pieces include gears, axles 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!
