See if you can find him on Ruckus' album cover (Hint: He's lurking in the background like some kind of disco genie):
They summoned him by rubbing a magic lava lamp.
Ruckus became kind of a big deal in Tampa, Florida, attracting a lot of young fans, mostly female. According to Hulk, "There was all this hot ass running around, you know? All of a sudden, before I knew it, there was a bunch of wrestlers at our gigs."
He recognized one of the muscle-men as the manager of Superstar Billy Graham, a famous pro wrestler, and started following him around. Eventually, Hulk asked if he could try out, and the wrestling crowd happily auditioned him by breaking his leg. When he came back after that, sans police or lawyers, they began his training, because wrestlers only recruit people who are insane. Ruckus wound up being the Hulkster's final band (not counting Hulk Hogan And The Wrestling Boot Band) before his wrestling career took off and he became known across the globe as that orange goblin who was great at wrestling but had chronic difficulty hearing when crowds were cheering for him.
