HEXBUG feels its way around sensing objects in its path and avoiding them. And it can even hear! You can control where it scurries through a hand clap- loud noise or table slap. The robotic bug will travel forward until it hits an obstacle or hears a loud noise. It will then backup in a half circle and then move forward in a different direction. Colors will vary. WARNING: Choking Hazard - Small Parts. Not for Children under 3 yrs.
