Insert the 20 double-sided learning blocks into the interactive Smart Star and it will respond with fun sounds, educational songs and phrases that enhance building play with learning content. For even more fun, try using learning blocks from other LeapBuilders sets in the interactive cube to unlock additional content responses. Get building with smart blocks for smart kids!
