#1 The Firefly Funhouse match
There are now two stipulation matches at WrestleMania 36 that we've never heard of. The first one is a 'Boneyard' match between The Undertaker and AJ Styles, while the second is a 'Firefly Fun House' match against John Cena.
If you immediately thought of the 'House of Horrors' match in 2017, it's time to forget about that. The circumstances were different and that stipulation was never going to get over. But Wyatt has done a great job of keeping the Firefly Fun House relevant and the only other Superstar who has entered it is Seth Rollins - though no explanation was given as to how he got there or how he exited or what happened when he left.
It was a great episode of Firefly Fun House, diving further deep into the psychotic personality of Bray Wyatt. The execution was done to perfection and it led to Wyatt inviting Cena to the Fun House for a match.
Expect something very different. It's going to be an outstandingly unique concept.
