When I was a kid i think I played this game on the old nintendo of this caterpillar thing that would eat things and get more balls attached to him... making him the caterpillar. and when bad guys would hit him, a ball on the caterpillar body would disappear.

I had a lot of bad things happen when I was a kid so I would make up places and things to block out the bad things. I really dont think I imagined this game though... any help???
