Role in episode
Squidward must stay at the Hotel Halibut after his house is being exterminated due to a sea urchin infestation. At the hotel, he is initially annoyed by the receptionist, but enjoys his room. SpongeBob and Patrick start running between the rooms, and come in on a room service cart after Squidward orders food. SpongeBob and Patrick explain that their rooms are right between Squidward's.
Squidward is unable to get away from them, visiting the spa, the gym, and the pool. He continually runs into them in the hallways, and starts panicking. SpongeBob and Patrick tell him about the annual Jelly-Con being held at the hotel, and Squidward is then brought into the convention.
Squidward tries to escape the hotel and wears a jellyfish costume. When the convention starts its "jellyfish mascot hunt," Squidward is chased across the hallways, but discovers a "zapper" in the costume and gives everyone an electrical shock. He calls at the front desk and has the hotel exterminated, filling it with a dangerous gas.
While the hotel is evacuated safely, Squidward is revealed to be dancing and singing in his room, wearing a gas mask.
