SpongeBob's Atlantis SquarePantis is a game starring SpongeBob and friends. The game is based on the television movie of the same name. The story follows SpongeBob and the gang as they try to escape from Atlantis, where they encounter Plankton in his newly acquired Atlantean tank.
The gameplay differs each level. In the first level, you take control of Plankton and his stolen tank, which can fire its ice cream cannon at the Atlantean defenders. SpongeBob and Patrick are trapped in a cave in the second level and must work together to get out. The levels become increasingly varied, with tasks such as taking photographs in a museum, driving a bus, and collecting treasure.
Throughout the game, you control different characters, each with their own unique abilities. You guide Squidward through an art class, where he must keep his pose by hitting buttons on the right moment. In other levels, you drive a bus to collect parts for repairs or sneak into the armory as Plankton.
The game ends with you taking control of an Atlantean soldier who is tasked with disposing of the amulet that brought the gang to Atlantis. The gameplay offers a fun and varied experience, with each level presenting new challenges and opportunities to use your characters' unique abilities.
