Water activated robotic fish toy from Zuru that realistically swims when submerged. Place in water and the tail fin makes life-like movements to propel the robot in five different directions, and up to 6ft underwater. Comes in a playset that includes a fish bowl for it to swim around in. Also included is a generous amount of never wet sand, that allows you to sculpt underwater coral reefs again and again, using the squeezy bottle and tweezers to shape it. Available in a variety of designs and comes with spare batteries.
