Bud is a character in Professor Layton and the Azran Legacy. He lives in San Grio, where he owns a restaurant. He tells Layton and the others about the "one true popoño" and how it is given to everyone in the town. They later discover that he had it all along and he gives them the original "Popoño", an Azran aura stone.
Bud runs an acclaimed bar and restaurant on the island of San Grio. He embraces the island's customs enthusiastically, and was eager to share the popoño-passing tradition with Layton and the others in order to bring a smile to Aurora's face.
