Joshua "Josh" Kling (born in the late 1970s) is an American actor who portrayed a newly-human Bowser in Stupid Mario Brothers before Austin Stevenson took the role. His tenure as the character was short-lived as he moved to Napa, California after Stupid Mario Brothers: The Movie was filmed. The change in actors was explained by Kamek, whom Bowser told to make him taller in hopes that he'd be stronger.
Kling currently plays the roles of:
- After moving away, Bowser returned in Season Five. Due to Kling not being able to portray him, Austin Stevenson replaced him as Bowser was made taller. An in-story explanation was also given for this change.
- It is possible that Kling was involved in the making of Bored of the Rings as he and Matt Provencal recited dialogue from it in the bloopers of Stupid Mario Brothers: The Movie.
