With the Mega Bloks Playful Centipede and 40 large sensory building bricks, kids can build a caterpillar with movement, chain bricks and a pull string on the front. Little builders can add a ladybug with a pop-up brick, a snail with a rotating and clicking function, and a butterfly with textured wings on the caterpillar's back. They can also try building a flower with a mirror and a bee with an abacus. These sensory bricks are perfect for little hands, helping to explore and develop auditory, tactile and visual skills.
