were the final two participants in the 1991 Royal Rumble, with Hogan getting the victory. After his stint with Hogan, Earthquake attained another WrestleMania victory, defeating former Hart stable mate Greg Valentine at WrestleMania VII. On April 1, 1991, WWF held a joint show in Kobe with Japanese promotion Super World of Sports called SWS Wrestle Dream. Earthquake appeared to face Kōji Kitao, in a battle of two former sumo wrestlers. Kitao and Tenta broke kayfabe by being uncooperative with each other. Kitao didn't sell Earthquake's attacks and shot on him. The match ended when Kitao was disqualified for kicking the referee. After the match, Kitao immediately grabbed a microphone and began telling the audience that wrestling is fake and that Tenta never could really beat him, as other Japanese wrestlers attempted to restrain him. The incident led to Kitao being fired from SWS.

When the match aired on WWF Superstars of Wrestling, footage of Earthquake landing on Damien was interrupted with cutaway shots to that show's "Events Center," although the incident aired uninterrupted and uncensored during WWF Prime Time Wrestling the following week. Later, Earthquake participated in a skit on WWF Prime Time Wrestling where he cooked "Quakeburgers" on a grill and served them to co-hosts Vince McMahon, Bobby The Brain Heenan, and Lord Alfred Hayes; later, Earthquake revealed that the meat was ground from Damien's carcass. Heenan had already eaten three or four of the Burgers and Hayes was curious about the meat. Earthquake mentioned the animal from which the meat was taken rhymed with quake and Hayes said they were snake burgers. Hayes got sick and nearly threw up. Vince was angry over this and knocked the tray out of Earthquake's hands which knocked all the burgers onto the floor. Roberts and Earthquake feuded throughout most of late-spring and into the summer.
