SpongeBob's Truth or Square is an arcade party game based on the episode of the same name. It was released on October 26, 2009 at Nick Arcade, the same date that the video game of the same name was released. Nick Arcade would close down later in 2010, and now this game is considered to be a piece of lost media.
After being entrusted by Mr. Krabs to keep the Krabby Patty formula safe, SpongeBob is overcome with grief for losing the recipe. He then relies on the help of the most unlikely companion, Plankton, who wants the secret Krabby Patty recipe for himself. With the help of his friends, SpongeBob must use Plankton's memory machine to retrace the happiest moments of his life to find the Krabby Patty formula in time for the Krusty Krab's Eleventy-Seventh Anniversary.
