Are there any toy story items sold only at disney parks?

Based on the available sources, the only verified information concerns the characters of the Toy Story franchise, not its merchandise distribution. No listing or mention of exclusive park-only items appears in the cited Wikipedia page or the knowledge graph entry. Therefore, we cannot confirm the existence of Toy Story products that are sold only at Disney parks. Without additional evidence, the safest conclusion is that such exclusive items are not documented. If you need definitive information, you may want to consult Disney’s official merchandise catalog or park retail listings.
