The Hexbug Larva will slither on a smooth surface but if it finds an obstacle it changes direction, sidestepping the obstacle. Kids can have loads of fun by placing it into an environment that is akin to the wild and find that the larva moving forward but avoiding the obstacles constantly and instinctively. They can also place their hand before it while it slithers forward and these creepy crawlers would immediately change direction and keep moving. This gives the toys an aura of a living creature for the kids and that gets them excited to keep on playing with them. Moreover, just the joy of watching these Hexbug Larvae slithering can involve hours of playtime for the kids and keep them engaged.
