SpongeBob's Truth or Square is a action-packed adventure game where Mr. Krabs entrusts SpongeBob with his secret recipe for the Krabby Patty, which he loses in the excitement.
The game follows SpongeBob as he searches high and low through Bikini Bottom to recover the lost recipe, aided by Plankton's memory machine that highlights his happiest moments.
During his search, players must defeat various enemies using SpongeBob's different forms, such as turning him into a sledgehammer or an explosive cannon. Players can also splash enemies with WaterBob.
