In this game Spongebob Squarepants: Grand Sand Fortress, Plankton is once again trying to steal the Krabby Patty formula, this time trying to get it from SpongeBob, who thinks he has it, so you will play a new and awesome defense game where you will protect this amazing recipe, doing so by playing a Tetris-like game whereby sorting blocks you will have to form the walls that will defend SpongeBob from various attacks. There will be waves of attacks, one coming after the other one, so withstand them all! The blocks have different levels of resistance, with sand being strong, the stone being stronger, and brick being the strongest, and depending on how well you form the walls you will get more powerful in your defense.
