I understand completely! I have a panda plush that I loved and still have - tush tag in shreds, etc. Right now he's on my old bed at my parents house.
Anyways, the story was that my cousin got the panda and when I saw it I grabbed it an ran away with it. They had to go to Wal-Mart and buy me my own. Well, years later I stayed at my aunt and uncle's house, and they still had my cousin's panda plush. It's in perfect condition. The nose is still stitched on with thread, tush tag and everything. So, now I at least know the info about it but it's still very generic.
So here I am living in the same town as the Wal-Mart were this plush toy was originally sold 20+ years ago and I go through a Goodwill shopping kick. I end up finding 3 more of my panda toy in brand new condition. It was crazy. My bear is rather large so it must have been one that tended to just sit on a shelf.

Never lose hope about finding more of your beloved toy! Even if it does turn out to be by a rather generic brand or something.
