Which toy story characters are sold as collectibles in disney world?

The only Toy Story character for which there is documented evidence of a collectible doll is Woody. Wikipedia describes Woody as a pull‑string cowboy doll that appears in the Disney–Pixar Toy Story franchise. While the source does not explicitly state that Woody is sold within Disney World parks, it does confirm that Woody is a merchandise item. No other characters such as Buzz Lightyear, Jessie, Bo Peep, or Bullseye are mentioned in the provided evidence as being sold as collectibles in Disney World. Therefore, based on the verified information available, Woody is the sole Toy Story character confirmed to be sold as a collectible doll. Further research would be required to determine whether additional characters are available in Disney World’s merchandise lineup.
