Craig the Devil was a secondary character of the SML series. He first appeared in Evil Bowser after Bowser summoned Craig to help him become more evil. Craig and Bowser only did tasks that were not very evil, such as making Chef Pee Pee clean spilled water. Craig would later become a friend of Bowser as well as a recurring character.
On July 28th, 2017, Logan confirmed that Craig would no longer appear in videos due to him getting them demonetized. This is likely because he is portrayed as the devil, which may have broken Youtube's Terms of Service. It is unknown if Craig will appear in The SuperMarioLogan Movie! or not.
