I had a Tamagotchi recently that my stepdad found. I kept it alive until I could give it to my niece. I had a hard enough time dealing with one of them, I don't know how someone could deal with ten of them!
I had a cardboard skeleton when I was a kid that my sister had made at school. It was small (40cm in height) but now I think it was funny how I took it off my sister and claimed it as mine.
