It could be a board game, video game, online game, or anything. It can be ideas from SB, or your spin-offs.
I'll do one:
SpongeBob SquarePants: The Great Snail Race
A very basic online game. Press left and right arrow keys repeatedly to race a choosen snail to the end of the finish line. In "Tournament Mode", you can unlock new race courses and characters. In "Arcade Mode", you can just race to your hearts content, and change the rules to your liking.
