The SpongeBob Movie Goofy Goober Guitar Mandela Effect refers to a widespread collective false memory regarding the 2004 film's climactic musical sequence. Thousands of fans vividly recall SpongeBob SquarePants shredding on a white, Gibson Flying V-style electric guitar while performing 'Goofy Goober Rock.' However, upon re-watching, it is revealed that he actually plays a white guitar shaped like a peanut. This discrepancy became a viral sensation in the early 2020s, with many users claiming the timeline had changed or that the scene was edited. It is frequently used in memes to illustrate the feeling of being gaslit by nostalgia or to discuss the broader Mandela Effect phenomenon in pop culture.
