I was clearing out my old room at my Mum's place and found a couple of toys that I was thinking about putting on Ebay.
One of them is a hard plastic figure, about 15-20 cm in height, made of molded plastic with fur like hair on the back. It's kind of humanoid, but overly cute, and makes a wobbly noise when you shake it as it's got a grid of holes on the bottom and some kind of sound feature on the inside. If I remember correctly, there was a cartoon based on them too. I have two, one in light blue and one in lilac/pink. Seeing as it's such a rubbish description, I've tried to draw one for you!
