The coin in question is actually a Warp Key, and it proceeds to open a portal to Munchmore, the food dimension! Papa Louie's old nemesis, Sarge the giant onion, and several burger monsters called Burgerzillas emerge from the portal, and the strange man takes off his disguise, revealing himself to be an evil radish man named Radley Madish! After receiving his order, the strange man flips a bizarrely shaped coin into the tip jar. Eventually, a strange man dressed in a heavy white trenchcoat and matching fedora approaches Marty and orders three burgers. Marty and Rita promptly enter the restaurant and begin serving the customers' orders.
On his way there, Marty picks up his coworker Rita and they both arrive at the Burgeria to find a large crowd of customers already there, eager to get their free burgers. Marty is preparing for a day of work at Papa's Burgeria, which is offering free burgers for one day.
