Graggle Simpson

Most claims made about Graggle include a backstory regarding the character's existence in the sitcom's lore.

Various permutations of the story claim that he was intended to be a self-insert of The Simpsons creator Matt Groening, that he was a much-beloved character among fans, or, alternatively, that he was removed due to poor viewer reception, or that he was added late in the show's run as a way of satirizing the show's perceived decline in quality.

A variety of fan works featuring Graggle have been produced, including fan art, edited cover art, screenshots and recordings of episodes of The Simpsons that include Graggle amongst other characters of the cast, and a modification for the 2003 video game The Simpsons: Hit and Run.

The earliest references to the character in English date from early 2021 on 4chan, in a post that establishes the prior aspect of Graggle being intended as Groening's persona, and also introducing two alternate names, "Yellow Matt" and "Weird Matt".

[6] The name "Gumbly" was likely inspired by Gumby, a claymation character who once made a cameo appearance in the seventeenth season episode "The Girl Who Slept Too Little".
