SpongeBob's Truth or Square is a platforming video game for the Nintendo Wii, wherein players assist SpongeBob in retrieving the lost Krabby Patty formula by navigating through various memories. The game features both challenging levels and puzzle elements, while players must outsmart the conniving Plankton, who aims to exploit SpongeBob's nostalgia for his own gain.
When SpongeBob misplaces the Krabby Patty formula, he must relive some of his best, and worst, memories to try and remember where it is. Unfortunately, the dastardly Plankton is trying to make him remember so he can steal it for himself.
