Role in episode
Karen reveals to Plankton that she ordered a baby for them, and a stork drone soon arrives at the Chum Bucket to deliver it. Plankton, not wanting a child, turns on the Chum Bucket's security systems and causes the building's glove to threaten the drone. However, the drone uses a laser to blast the Chum Bucket's roof open, allowing it to safely deliver the baby to Karen.
It is based on the myth that babies are not born, but instead delivered to their parents via storks.
He may have been the drone that told SpongeBob that Karen and Plankton are having a baby.
