Appearances in SuperMarioGlitchy4's videos
Following his debut, Shrek only appeared in cameos and archival footage.

SM64: Cooking with Bowser & Mario 2!
This is Shrek's first and most prominent appearance in SMG4's bloopers. In this video, he was created as a result of a chemical reaction that occurred after Mario added a Super Mushroom to a bowl of presumably unfinished Tubby Custard with weed. Shrek then proceeded to rape Bowser, destroy Mario's restaurant, Cafe Mario, knock a red Yoshi out of his chair, hit SMG4, and dance with a manly version of Waluigi and the girls from the original Caramelldansen video before rocketing out of the building towards the moon, all to the song Caramelldansen. Later, Mario is traumatized because he believes Tinky Winky and Shrek are connected to the Illuminati.

Retarded64: Mario for Hire.
Shrek makes two other cameo reappearances in this other video for a few seconds, both at the "Super Mario Business Time" in an office, on his computer at the background. The first time is when the phone is ringing, and the second is when Trevor Phillips of Grand Theft Autos V accidentally shoots Mega Man Volnutt when he tries to assassinate Mario.
