Gumbly Simpson or Graggle

Gumbly Simpson, also known as Graggle, is a fictional character from The Simpsons who was supposedly removed from the show due to poor viewer reception. However, this is just a hoax and Graggle never actually existed. The character is most commonly portrayed as a yellow, unclothed, alien-like humanoid with a large mouth and three strands of hair. He is often seen alongside members of the Simpson family, and some fans believe that he was intended to be a self-insert of The Simpsons creator Matt Groening. Others believe that he was added late in the show's run as a way of satirizing the show's perceived decline in quality. Regardless of his origins, Graggle has become a popular internet meme and has been featured in fan art, edited cover art, screenshots and recordings of episodes of The Simpsons, and even a modification for the 2003 video game The Simpsons: Hit and Run.
