I got this toy from a charity shop the other day, but I have no idea where it came from. It makes high pitched noises like it's trying to talk and likes running round my desk and will go to sleep when left alone. It seems to sing tunes sometimes as well.

It says it was made by TOMY in China on the bottom.

Here is an image, it looks japanese to me.

Maybe this is a Pokemon character,similar to the ones on this link-

Although the brand Pokemon is Japanese, it maybe manufactured in China.

Oh I'm pretty sure that is a micro pet! I've had a couple. I had a mouse and a pony. Yes that is a micro pet!
