The next generation of Robo Fish is here, with new designs based on fish you would find in the deepest parts of the sea. The new fish include the colourful wimple fish and the more sinister looking angler fish (complete with a light-up tip at the end of its lure). Just like regular Robo Fish, these small aquatic robots are water activated and swim just like real fish as soon as they enter the water. Their rear tails swish from side-to-side and power them through the deep where they can move in all directions to fully explore their underwater environment. There are three wimple fish designs and two angler fish.
