Yes, toilet paper. I couldn't use it for a while because my house had some problems with bugs and stuff. (not mentioning what kind) so it had to go down in to the basement. Then, when the problem was fixed, we sent it back up to my room. It wasn't working, so I thought it was all dusty. I cleaned it all out with a bathroom's toilet paper. ALL of it.
Your grandma has it? Figures, the nintendo is like 20 years old.
