Shrek is a main character in SuperMarioLogan. He is an ogre who enjoys eating cheesecake, and taking craps. He nicknames everyone "Donkey" (Sometimes he says their most outstanding feature and then "Donkey" I.E: Black Yoshi=Black Donkey, Toad=Mushroom Donkey).
Shrek was a background character in some early SML videos, but his first main appearance was in "Main Character Judging", where he appeared for the first time, along with Tour Guide for Today, Mama Luigi, and Poochie the Taco Bell Dog. He won the honor of being the next main character, and chose Poochie and Tour Guide to be secondary characters.
He appeared along with Mario and Tony in "SuperMarioLogan Watches 2 Girls 1 Cup" where he, along with Mario and Tony, is disgusted by the video. He played Santa Claus in SML's 2008 Christmas Special. He also killed Toad in the Toad Death Game, and starred in his own short film, "Shrek's Big Crap".
