How do i book a character appearance for a toy story event?

Quick Answer
The available evidence does not provide any details on how to book a character appearance for a Toy Story event.
Explanation
The provided sources about Toy Story 5 contain only production details such as the director, writers, cast, and plot summary. No information is given regarding event planning, character appearances, or booking procedures. For most Disney or Pixar‑licensed events, the usual practice is to contact the official Disney or Pixar customer service or the event management department that handles character appearances. They typically handle scheduling, fees, and location logistics. However, because this process is not documented in the sources we have, I cannot give a step‑by‑step guide. To obtain accurate instructions, you should reach out directly to Disney’s official customer support or the venue hosting the event and ask for the specific booking procedures for Toy Story characters.
