SpongeBob Town/SpongeBob Online is a lost SpongeBob MMORPG that was supposed to be released in 2012 or 2013, but got cancelled after it's first technical test. Information on it is kind of obscure but stuff should be findable.
Plot: The mayor's dark scheme has jeopardized the city of Plankton into a huge explosion. Mr. Krabs, seeing the big cash opportunity, gathers up people for re-construction business.
SpongeBob Online brings the world of Spongebob to a MMO game experience. It's a social platform where many players can interact with each other while enjoying diverse games together.
I helped C&B Extra make a video on the game that you can watch at www.youtube.com/watch?v=zCbJgCQuvlI It helps explain a bit of stuff about the MMO with the information I gave him, and it's an amazing video overall.
