Spongebobstein (sometimes stylized as SpongeBobStein) is a mod for Spear of Destiny, made by Ian Summerfield.
It features 21 levels and many new hand-drawn graphics, and features characters and traits from the TV show Spongebob Squarepants.
Humorous and silly in its outlook, as it is based on cartoon show, the mapping is nonetheless pretty good as the atmosphere is seeped in all things Spongebob.
Initially released as a demo on August 16, 2003 a full version was finished in November 2003 but Summerfield would not release it due to not having permission to do so from the creators of the TV show. He would gladly send it to those who sent him an e-mail requesting it, though.
It was only released as a full 21-level set on the Dome on March 3, 2004.
No source code changes are featured, and it is thus playable in SDL.
