Hello!
I've been trying to remember a toy, im not sure if it's from the 80s or 90s..but it was a teddy bear, which looked to be good, but you could turn his head around and his paws to turn him evil...I remember it was yellow, and had a white and green striped shirt..I hope that someone could remember this, thanks :)

Is this it? It's called a Were-Bear.
