How can i verify if a toy story toy is an original disney world exclusive?

The evidence supplied includes only a knowledge‑graph entry for the Toy Story franchise and a Wikipedia article about Toy Story 5. Neither source discusses merchandise, exclusivity, or methods for authentication of Disney World toys. Therefore, based solely on the verified evidence, it is not possible to answer your question. In practice, people often verify authenticity by checking for official Disney World packaging, unique serial numbers, holographic labels, or by consulting the official Disney World or Disney Collectibles websites. However, these methods are not supported by the evidence provided here.
