Most robot pets may not be easily mistaken for the real thing, but that's not likely to be the case with the ChouChou Electric Butterfly, which might even have a few people reaching to free it from its jar. Unfortunately, it's the jar that keeps the butterfly "alive" -- it has some AA batteries in its lid that apparently allow the butterfly to respond to vibrations and flutter about. That may not sound like much, but the effect is pretty striking -- see for yourself after the break. Of course, just because it's simple doesn't mean its cheap. You'll have to shell out a hefty $76 to bring this one home.
