ZOOB is a building set with a difference�the pieces move after kids put them together. So kids can play with their creations, instead of just looking at them. ZOOB JR. provides ZOOB's award-winning creative play with softer pieces designed for young children. ZOOB JR. pieces are made with a special memory material that flexes and goes back to its original shape, so they bend, move, and snap together snugly. And just like ZOOB, ZOOB JR.'s open-ended versatility lets kids build anything they want to build as it sparks young imaginations.
