Template:Creature The Horrifying Sweaty One-Armed Monstrosity[1] is a creature who appears during the event of Weirdmageddon.


In "Weirdmageddon Part 1," The Horrifying Sweaty One-Armed Monstrosity encounters Dipper as he attempts to break into Gravity Malls in search of his friends. He demands that Dipper climb into his mouth, which Dipper ignores in terror, much to the monstrosity's frustration. He later appears when Wendy and Dipper are trying to avoid Gideon and his henchmen, where he eats one of the Discount Auto Mart Warriors. He also appears during the episode's end credits, still desperately trying to convince anyone to climb in his mouth. He finally gives up and leaves the screen announcing that he needs to call his mother.

While Weirdmageddon was being reversed in "Weirdmageddon 3: Take Back The Falls," he was sucked back to the nightmare realm.


He consists of a gigantic man's head, with a round nose, a five o'-clock shadow, thick red eyebrows, and red hair on his temples. Attached to the top of his head is a muscular arm which he uses to drag himself around.






  • Louis C.K., the creature's voice actor, improvised most of his role during the end credit scene of "Weirdmageddon Part 1" where he says, "I gotta call my mother." In fact, there is nearly 30 minutes of him improvising different ways the monstrosity could beg someone to get into his mouth.[2]
