Robo Fish are robotic fish which swim with lifelike movements and have water activated pressure sensors that turn the Fish on as soon as it comes in contact with water! Watch as your Robo Fish ducks and dive as it swims at different speeds. It's like owning a real fish, without the mess! The perfect gift for all kids that want a pet and for all parents that don't like the upkeep! Simply drop it into water and watch it zoom about the tank.
