Spin-Offs are works on SBC that relate to SpongeBob Squarepants (hence Spin-Offs). They can be found in Spin-Offs and Lits, under the Squidward's Art School board.
Spin-Off work on SBC has been dropping since 2012, which has frightened everyone on the site. It is believed that the lack of reviews for users Spin-Offs is the primary cause for less activity with Spin-Offs. Users have been making attempts to save Spin-Off reviewing by making "The SBC Spin-Off Club", which is similar in format to the "SBC Weekly Episode Club"
As of late 2012, Spin-Offs have risen in activity again.
