In this game, a sea bear is chasing SpongeBob, Patrick, and Squidward. The player has to draw anti-sea-bear circles around them so that the sea bear will avoid them. The player also has to draw circles around marshmallows to proceed to the next level, and avoid drawing them around the sea bear because it attracts the sea rhinoceros. There are also objects like flashlights, cubed cheese, and sombreros which attract the sea bear to it instead of the characters. There is a limited amount of ink the player can use which recharges after some time. If a character runs into the sea bear, they get attacked and an ambulance arrives to take them to the hospital. It is game over when all three characters have gone to the hospital.
Nick Magazine features a code to unlock the clarinet for this game. The code is "cheeks." The clarinet gives unlimited ink.
If a sea rhinoceros appears, Anti-Sea Rhinoceros Undergarments will also appear. Drawing a circle around it make the Sea Rhinoceros avoid the characters similar to other objects. Additionally, the Anti-Sea Bear circles also make the Sea Rhinoceros avoid the characters.
