First, he gives the fruitcake to SpongeBob to test it, but he is resistant to the jerktonium, and upset that his plan failed, gives his fruitcake dispenser to SpongeBob, who promptly distributes the fruitcake to all of Bikini Bottom, turning all the residents into jerks, like Plankton intended. However, he reveals to Karen his latest discovery: jerktonium, the substance that will turn anyone into a jerk, and cooks into fruitcake he intends to spread around Bikini Bottom. Plankton, however, is miserable, having committed so many naughty acts, he is on the naughty list and won't receive his Christmas wish - the Krabby Patty formula.
