The SpongeBob Fanon Wiki, abbreviated SBFW, is a SpongeBob SquarePants fansite where users can create their own spin-offs, episodes, and other fanmade content for other users to read and review. It was founded on November 8, 2008 by Arre 320, and is currently the second largest SpongeBob wiki, with 8,275 pages, after this wiki.
The wiki was created in November 8, 2008 by Arre 320. In 2013, a collaboration with ESB was formed along with SpongeBob Universe, and later as a project. However, due to tensions between the administrations of the two wikis, the group was peacefully dissolved with a farewell address made by AMK152.
