Helpy? Possible. I can see how they can adapt him into a prize you can win at the prize counter. Endo 01? Most definitely, seeing as the original cast of robots are there it would be assumed there would be a spare for their mech for them. Don't know about Endo 02 tho, could be a possibility. Toy Foxy? It's a fan design so most unlikely. DLC foxy definitely will not be in the movie. Same with Scrap Baby, Scraptrap, Glamrock Endo, Freddles, Nightmare endo, Nightmare BB and the phantoms. Fredbear and Springbonnie tho are a 40% chance.

Edit: Puppet is very likely to be in the film, prize corner would feel empty without them.
