Fish Out of Water

This is odd:

This Blood Parrot fish rolls the contraption around just by swimming around in its bowl. The sensors and the onboard computer detects [sic] which direction the fish is swimming in, then directs the wheels accordingly.

Put some weapons on it, and the family fish can finally give the cat a little quid pro quo.

Kind of reminds me of Professor Wernstrom's "walking fish suit" from Futurama.
