There are tons of ways to stack these wooden robots - use all of them or just a few, use them upside down or sideways and experiment with different shaped "stacks". Not only are the robots entertaining, they offer kids a playful way to develop spatial thinking and problem solving skills, and let them experiment with balance. Plus, they look awesome lined up on a shelf! 

The set includes 9 multicoloured wooden robots that interlink in many different positions to create remarkable shapes. The fun, retro styling appeals to kids (and adults) of all ages!
