At the Chum Bucket, Plankton is introducing a new chum sauce, which melted through the pan and later through the floor. Just then, the alarm sounded, informing Plankton about a customer. Plankton went to receive the order, only to find that he wanted a Krusty Krab product, so Plankton told him to get those foods and beverages at the Krusty Krab. As he complained over how the people won't buy his food, he felt that Karen wasn't a good employee to him. Then, he threatens to replace his wife with much cooler machines, all three which failed to operate steadily. One of those machines was a toaster with arms and legs, which exploded, but survived. Another which is made of mostly liquid, but popped open and lost its liquid and also survived. The last being a windmill with a hairdryer on its back. Soon, the new inventions were acting aggressive toward each other. Plankton stated that he has had enough of Karen. Karen left a note saying that she's tired of being blamed for his failures. Later, Plankton sics his machines on the Krusty Krab, but it fails. He sees Karen, who has come back to get her things. He apologizes to her and she accepts his apology. They go back to the Chum Bucket together.
