Radley Madish had a very deep grudge against Papa Louie and his customers. Before the events of Papa Louie 2, he met Sarge and the two decided to work together to destroy Papa Louie's empire. Radley disguised himself by wearing a trench-coat and entered Papa's Burgeria during the restaurant's "Free Burger Day" promotion. He threw a warp coin into the tip jar, causing 28 customers to enter the Land of Munchmore, filled with baddies Radley created. Sarge is fought on level 4 in Fort Onion, and Radley Madish is battled on level 9.
After his humiliating defeat in the last game, Radley fired Sarge and hired a man named Luau LePunch. He came up with an even more diabolical and sinister plan: to hijack the Seaside Freezeria cruise. He kidnapped Alberto and Penny and forced them to make his Sundaesauruses, which he used with other new enemies to keep Captain Cori from stopping him and freeing the other captives.
