The Noki Director is an elderly Noki that is the director of Pinna Park in Super Mario Sunshine. He was first seen in Pinna Park telling Mario how the park become less popular because it hasn't had a new attraction. After Mecha Bowser emerged out of the small pool of water at the northwest end of the park, the Noki Director believes that the spectacle is a new show and that Mario and Shadow Mario are its stars. To improve the show, he allows Mario to use Pinna Park's roller coaster to defeat the rampaging robot. When the battle ends, the Noki Director calls Mario a hero for emerging triumphant and putting on a great show. He is later seen throughout most of the missions of Pinna Park, as well as the ending scene of the game.
