Hexbug Nano Hive Habitat Set introduces the first transportable environment that enables your young architect to customize the design within a Habitat Set system. Each Hive Habitat Set features a center ramp for Nano bugs to freely access multiple levels and a floor spotted with attachment points where kids can pop in their choice of new playground accessories. Kids can personalize their playground by repositioning the pegs and rotatable flags, which direct the Hexbug Nano toward ramps or other obstacles, including a seesaw and a merry-go-round for the playfully energetic critters to explore. CPSIA approved.
