It's almost Christmas in Bikini Bottom and lots of Bikini Bottom residents are sending letters to Santa at the Bikini Bottom Post Office. However, Plankton does not want the letters to go to Santa, so he has designed a special Jelly Claw which will allow him to grab the letters out of the Bikini Bottomites' hands.
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 Bottom 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 is 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 you swipe the letter from her you lose points. If you let a person enter the Bikini Bottom Post Office, you will lose a life. The game ends when you lose all 3 of your lives.
