In each area multiple fish will be around, most of them resembling the character you are looking for. Every fish has a twin. The game is played by using SpongeBob's paddle ball to plunk the pairs of twins, which will disappear if they are identical, until only one character is left, the one you are looking for. Plunking the character you are looking for makes you have to restart the area. There is also a timer, and you lose the game if it runs out. Bubbles can also be clicked for bonus points. At the end of every level, there is a bonus round in which many bubbles, jellyfish and blowfish appear which can be clicked for bonus points. The game ends when you beat the final area or run out of time.
