A Swipin' Stu is a variety of Strollin' Stu appearing in the game Super Mario Sunshine that appears in Pinna Park after completing a certain mission.
Swipin' Stus resemble a cross between the Soarin' Stus and the character Mario. If the player looks closely, they will also see that it has darker skin than a typical Strollin' Stu. Swipin' Stus attack when Mario walks beneath them, attempting to land on him. If a Swipin' Stu succeeds, it will steal Mario's cap. Mario will then suffer from a sun-stroke and slowly lose health. To retrieve his cap, Mario must either Ground-Pound the Swipin' Stu's head and take it back, or enter Pinna Park for the game to reset it back.
