Sorry for the late reply everyone I was out this morning. soufflé, I didn`t know you were talented with the knitting needles!
I love that little bean shaped knitted hamster shown in green in the link, although a robo would be more of a round ball shape! A plain light-ish brown one more like a robo would be good! Especially if it has the small black button eyes, the pale feet, ears and tail and if possible, the little eyebrows!
I was in a charity shop this morning and payed 20p for a Burger King toy plastic hamster I found in the kiddies toy section.
It zooms forward when you twist the disc under it`s belly and it resembles a golden hamster in colour so I was well chuffed! Here is a blue one but mine is light brown. Mine doesn`t have the car though!
