In an interview with Inside The Ropes, Braun Strowman revealed that Bray Wyatt himself came up with the Firefly Funhouse segments and not a WWE writer:
“Oh man, Bray Wyatt, his mind is like no one else’s. The things he’s capable of thinking of and coming up with. Everything is his idea, all this Firefly Fun House, everything. It’s great to have Bray back, especially in the locker room for morale and everything with the guys. He is one of our top stars, he’s one of the locker room leaders, and he’s one of my best friends.”
