It’s not just a rumor, she is one of two characters that get hazard pay. The other one is Ariel in Fantasmic! After the boat with all of
the characters go by, all of them have to run to one side of the boat for shelter from the fireworks. They don’t have time to move Ariel though, so the other characters just put a bag over her and leave her when the fireworks go off. My Aunt took the Keys to the Kingdom tour, and I think she said that they said those 2 get a full day’s pay for the one appearance they make (someone can correct me if I’m wrong about how it works exactly, but I do know they both get hazard pay).
