This old school nintendos, I miss those!
I would have to say either sky dancers or my gigapet...miss those days!
There are two the one I had as a young child was a Salerno Butter Cookie Truck. And the other would be all my Barbie stuff
My wind up bulldozer. It was metal, you would wind it up with a key that stuck out from the side and it could climb a 50 deg ramp.
