I collected Pokemon cards when they are really popular. I didn't really trade them but I bought them so often. Now I only have the actual Pokemon and got rid of all of my energys and trainers. I also collected Yu-Gi-Oh cards.

I had so many Tamagotchis. I had four real ones and about the same of cheaper ones. I would take them everywhere and make mum look after them while I was at school. I would be upset when my dog in my favourite one would run away.

I collected Beanie Kids. (I think they are called Beanie Babies in the UK. Not the TY ones though) I have 104 at last count.

Oh and tazos. I used to have so many of those and play against my brother.
