Since King Neptune is bald, he is very concerned about his crown because it can hide the head of a little hair so that the residents cannot see it. But unfortunately, someone stole it while he was sleeping, so he became extremely angry. SpongeBob and Patrick were tasked with investigating, and regaining the crown before things got worse. After a while, they found out that the thief was Plankton. He sold it to criminals in Shell City. However, the journey to this city contains many dangers as they have to overcome the land containing monsters, including the giant Cyclops. However, if they were unable to retrieve Neptune’s treasure, Mr. Krabs would be blamed and punished for death.
