Bring your own Blue Hexbug Crab to life in your living room. Shaped like a miniature robotic crab, the Hexbug Crab crawls across floors and tables looking for dark corners to hide in. When it finds one with its light sensor, it stops and 'falls asleep'. When you make a loud noise, it wakes up and scuttles out of hiding. Loud noises can also make the Hexbug change direction when it's walking around. Hexbug Crab uses 2 x LR44 batteries, which are included.
