Robotic fish at Tokyo toy fair

Created bu TakaraTomy Arts and released at the 2012 Tokyo toy fair, this cute gizmo costs 15 € a pop. it runs on batteries that power the fish's tail.
It then moves randomly on it's own, with its tail respectively moves slower or faster.

pretty cool, they act pretty lifelike i`d get a couple, i`m sure the cat would love these.
