Season 6 is the sixth season of SMG4's channel, and it aired from January 3, 2016 to December 18, 2016, and contains 54 episodes. In this season, Luke's brother Kevin began working full-time on the series, providing the voice of Fishy Boopkins and also pitching ideas, as well as Martin Yeung, who would be the editor of the episodes. This season was responsible for bringing two major characters to the series, Fishy Boopkins and Bob.
This season gave a redesign to Luigi's SM64 sprite in order to distinguish himself from Mario. This season was also when SMG4 started to favour Garry's Mod than Super Mario 64 but was overused. It was also the season where many side characters, such as Kermit, Woody and Shrek appear. Most of the episodes in this season were random-based, not much like previous seasons.
