Toddlers can build and explore with the Move 'n Groover Caterpillar and 40 large building blocks featuring sensory functions. They can create a caterpillar using movement blocks, chain blocks, and a pull string at the front to set it in motion and groove. Little builders can construct a ladybug with a pop block, a snail with a twist-and-click feature, and a butterfly with textured wings on the back of the caterpillar to accompany it. They can also build a flower with a mirror and a bee with an abacus to enhance the scene. These sensory blocks are perfect for small hands and help discover and develop auditory, tactile, and visual skills.
