AnimalCrossing is Missing...

Yup, for a week now I have lost my copy of AnimalCrossing Wild World on the DS, and so far I have turned my room inside-out twice to find the tiny goddamn game card. I swore that the last time I played it was in my room last Sunday (8/10/06), however I noticed that the game wasn't in my DS or my pouch that I keep my DS games in. I've missed out on the Acorn Festival today due to it missing and I'mm pretty damn annoyed. Where the hell can it be, knowing my luck it's going to be somewhere totally obscure and random that I would never think is there! But yeah, please give me your luck cos I'm having withdrawel symptoms without my AnimalCrossing! :(
