Instructions
Run around the outer perimeter of the battle area, avoiding the boss's saw-hand attacks. Wait for the boss to pound its head on the ground three times. After the third hit, the submarine gets stuck in the ground.
Run to the back of the boss and hit the exposed target. Run away after you hit the target because the boss's head will become unstuck and the boss starts attacking you again.
Repeat Steps 1 and 2 two more times to defeat the submarine-headed boss. You will receive coins and the Sandy's Iced Tea Glass happiness object for home decoration. A cut scene follows your victory, in which SpongeBob meets Sandy Cheeks.
