Sometime in 2016, Climax Development sold off all of their assets at the time on eBay, which included hundreds of development discs, including the assets of SpongeBob SquarePants: SuperSponge. On one of the development discs for the PlayStation version, three pictures with the common filename "Naughty.jpg" can be found, and contain three sketches of SpongeBob having sex with Patrick, Patrick having sex with Sandy while holding an unknown object, and what can only be described as a Sponge Dominatrix.

There are unused death animations for SpongeBob in the PlayStation version.
