#4 An animal
I'm guessing that bringing an animal on screen for a segment is a lot more difficult to pull off now than it was during the era of Jake Roberts. But as we've seen in the past, Vince McMahon gets what he wants. While it may be difficult, I'm sure it is not impossible if you consider the fact that Cody's dog made an appearance in AEW.
I'd love to see Rowan as the new Jake Roberts, carrying a snake to the ring. And I wouldn't mind it if WWE does the exact opposite in his case, with him carrying a parrot or a kitten to the ring, something that adds a dimension to his character, a fearsome man with a cute and lovable animal. Remember the time when Scott Steiner came to the ring in Nitro, with an actual tiger?
It's something that's not been done in WWE for a while, and I'd love to see how far up the ladder Rowan could potentially go with this particular gimmick.
