Help Plankton use his Jelly Claw to steal the letters by clicking to try to grab a letter. Bikini Bottomites will move at different speeds but Plankton's Jelly Claw cannot move with them, so the player is required to click a certain distance in front of the Bikini Bottomite depending on their speeds. The main characters are special and are generally more difficult to take the letter from. SpongeBob moves up and down in a zig-zag motion, Pearl requires two clicks, and Sandy wears rocket boots making her much faster and harder to grab the letter from. Karen, on the other hand, is the slowest moving character making her the easiest character to swipe the letter from. However, if the player swipes the letter from her, they will lose points. If the player allows someone to enter the Bikini Bottom Post Office, they will lose a life. The game ends when the player loses all three of their lives.
