Teku Teku Angel Due
virtual pet pedometer

They come in several colors....pink, blue, and clear green are the only ones I've seen so far.
My favorite is the clear green.  These are mine.

Btw, it doesn't usually have Japanese text on the main screen. That's just the startup screen.
(Sorry about the poor quality image. I'll replace this with better photos very soon)
