Gameboy Color-Frogger 2
I also have a Nintendo Wallet. It has the original NES controller on the front. Sometimes I pretend to play my old Nintendo (NES) games with it. I am not insane.
***About Ham-Ham Heart Break: The reason I got this game is because somebody found it lying on the ground in our church. They took it to the office and since no-one claimed it in a week they gave it to my mom (who works in the Parish Office) and she gave it to me. Why it was in the church I don't know. Also, it is sort-of an adventure game which is cool.
(I would like to hear what Nintendo Items YOU have. Also post anything Nintendo-y.)
