Are toy story characters available for birthday parties at disney?

The only verified information available is a list of characters from the Toy Story franchise, which includes the films Toy Story, Toy Story 2, Toy Story 3, Toy Story 4, Toy Story 5, and Lightyear, as well as related TV specials. None of the sources mention birthday party services, character appearances, or Disney's event offerings. Therefore, there is no evidence to support the claim that Toy Story characters can be booked for birthday parties at Disney.
