At some point in the existence of the game's developer Climax Group, all of their assets at the time were sold off on eBay, including the assets of 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.
