#4 Subtly putting the entire roster on notice
There are multiple Superstars who've had puppets from the Firefly Fun House appear during their backstage segments. The Miz has been stalked twice, Kofi Kingston once, Daniel Bryan once and Carmella once too. It may be Bray Wyatt's way of telling the WWE roster to just 'let him in'.
There's a moment from 'Fear the Walking Dead', the crux of which is that the most dangerous people don't have to say that they are dangerous to prove that they are. This is precisely what is happening with Bray Wyatt and his puppets. The message is loud and clear and is a hundred times more effective than the traditional professional wrestling/sports entertainment promo, in my opinion.
A WWE Hall of Famer isn't a John Cena fan. More details HERE
It will be interesting to see who the next victim of the Firefly Fun House is. Expect yet another cameo to take place on WWE SmackDown Live.
