I'm looking for some old pokemon toys

Hello, I'm currently on the search for pokemon that came in this collection of keychains. All I have is this image of a zapdos as a reference. I know it's a long shot, but if anyone here knows any information about the distributor or series, I'd love to get more like him, especially articuno and moltres.

Is it part of the Burger King promotion run?

Oh god I remember that the fluffy pikachu toy that they had etc

I used to have the Pikachu one. I think it came out of one of those pound coin machines at toys r us.
