In each area multiple characters will be around, most of them resembling the character the player is looking for. Every character 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 the player is looking for. Plunking the character the player is looking for makes them have to restart the area. There is also a timer, and the player loses the game if time runs out. Bubbles, jellyfish, and blowfish 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. There is a total of 8 levels in the game. The game ends when the player beats the final area or runs out of time.
The Chum Bucket is the only location in this game that doesn't appear in the actual episode it's based on.
