Smolderin' Stu

A Smolderin' Stu is a type of Stu that appears in the game Super Mario Sunshine. It is distinct from Strollin' Stu due to its ability to be covered in flames, yet be apparently unharmed. Mario will get burned if he touches the flaming enemy. If the flames are put out, it can be seen to have a reddish skin color. It is very rare, only appearing at Pinna Park in the "Mecha-Bowser Appears" mission and Sirena Beach in the "King Boo Down Below" mission.

Smolderin' Stus can easily be destroyed by a well-aimed squirt of water from F.L.U.D.D.. Both Smolderin' Stus and the common Strollin' Stus appear in the King Boo boss fight.

Trivia

 * Smolderin' Stu's name is also seen as one of the default high scores in Mario Golf: Toadstool Tour.
