Huh, you'd think he would have posted something himself about this if it was something he really needed help with.
With that said, no, couldn't really help with that. The plushies you're looking for, if they even exist, had to have been made sometime back between probably 1998 and 2005 I would guess. But I'll keep my eye out. You never know what will turn up.
I saw charizard being sold on the disney store ( years ago, when i was small ), sadly i never got him, so i wouldnt be able to sell it to you. I got a giant charmander instead, he was the last one on the store. Ebay is always tricky, a friend got 500 bucks stolen when she was trying to buy a PSP, amazon got some cute plushes tought .3.
