Bell plush are possibly one of the rarest sets of Pokémon plush in existence. They were given out as arcade prizes in Japan between 1996 and 1997. I was extremely lucky to find a Moltres one still in its box.
A Moltres UFO plush made by Banpresto. It is extremely rare, and in addition it is hard to find in good condition due to the plastic on its wings which cracks easily
A Moltres finger-puppet plush made by Tomy.
Another Tomy plush, which interestingly enough, also happens to be a finger puppet.
This was released in a Burger King promotion featuring some of the first 150 Pokémon.
