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.
