I have that Barney game! My brothers and I use it to stash gift cards. It was one game that we owned back in the day when my brothers were really little.
We actually pulled the game out at an anime convention once. People sat down to play it, and started timing each other for the fastest completion of levels.
Ah, I should have opened it and checked for a secret giftcard then. Hell, I'd have been happy with a secret stash of Krokodil even.
