last time i was at game stop a couple months ago looking for N64 controllers, they had stacks upon stacks of yellow pikachu 64's...not sure if the situation near you is the same, but i just thought i'd help in case no one here has one...that they want to admit to.
check with samuraiX
He has heaps of useless crap. I bought a boxed donkey kong n64 from him. Last I was at his house he had a bunch of n64's not sure if he has a pokemon as I don't recall. Couldnt hurt he check with him.
