Visiting a carnival provides the opportunity to meet toys who are prizes to be won, but what happens if these toys are never given away.
This is the deep character study I want in Toy Story 4!
Toy Story 2 covered toys that remain on display/in boxes rather than are played with, and Toy Story 3 saw the main characters being dropped off at a daycare, where they were handled, shall we say, violently.
How would living in the carnival that long and never having a proper home affect their state of mind.
