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 Atlantis, but things don't go as planned.
The gameplay varies from level to level. In the first level, you play as Plankton, using his stolen tank to fire an ice cream cannon at the Atlantean defenders. Later levels feature different characters taking control of SpongeBob and friends, each with unique abilities and objectives. You must work together with Patrick in the second level, take pictures for SpongeBob in the third level, and drive a bus to collect parts in the fourth level.
In later levels, you'll play as Sandy, firing a gun at gems in the fifth level, or Squidward, keeping his pose for an art class in the eighth level. Patrick takes on a photography challenge in the ninth level, while Plankton sneaks into the armory in the eleventh level. The game ends with the final boss fight, where you play as an Atlantean soldier tasked with disposing of the amulet that brought the gang to Atlantis.
