HEXBUG Aquabot Jellyfish - colors may vary;

Loaded with smart fish technology, this new Jellyfish will amp up the action of your robotic aquarium with its vibrant inner glow and 15 pre-programmed swimming routines. Watch as the Jellyfish uses its 18 tentacles and powerful ducted impeller motor to spin and swim gracefully as it explores its new home. And now, for the first time ever, you can adjust the HEXBUG Aquabot's buoyancy (using adjustable weights in battery door) to give your pet customized swimming patterns. To turn on your Jellyfish, simply drop it in water to activate its automatic on and off sensor. After 3 minutes of swimming, it will go into sleep mode to preserve battery life. Wake your underwater friend in 3 different ways: simply run your fingers through the water, touch the Jellyfish, or tap on the side of the tank.
