Are there exclusive toy story items sold only at disney theme parks?

The provided sources do not contain any information about Toy Story merchandise or its availability at Disney theme parks. One source only confirms the existence of the Toy Story franchise, while the other discusses the 2023 film Wish, which is unrelated to Toy Story. Because there is no mention of exclusive Toy Story items in the evidence, I cannot confirm that such items exist or are sold exclusively at Disney theme parks. Additional reliable sources would be required to substantiate any claim about exclusive merchandise. Until such evidence is found, it is prudent to treat this claim as unverified.
