Jellyfishing are floating around Jellyfish Fields. SpongeBob and Patrick watch the jellyfish, then run to collect their gear (Nets, glasses, saftey gear). SpongeBob and Patrick try to catch a Jellyfish but get stung while running away from it. They land at Squidwards house who is just about to go for a bike ride. Squidward rides off laughing until he meets a Jellyfish which gets stuck in his mouth. After trying to get rid of it he slides down a cliff and explodes.
The next morning Squidward arrives at his house in a wheelchair in bandages. SpongeBob and Patrick greet them in surprise. Squidward tries to leave but SpongeBob and Patrick refuse, so Squidward is forced to stay. They start with some soup but after many attempts of blowing SpongeBob stops Patrick from burning Squidward even more. Next is a tune on the clarinet but after SpongeBob licks his lips Patricks stops him from playing.
So they go Jellyfishing which gives Squidward the chance to run off. But they don't let him so he is still forced to stay. Patrick rams a jellyfishing net through his hand, causing Squidward great pain. Squidward barely shows interest in catching a Jellyfish and SpongeBob and Patrick fail to show him how to catch a Jellyfish to the song "The Blue Danubae". While SpongeBob and Patrick are being stung Squidward locks his eyes on a Jellyfish after he gets stung by one. He runs after it but the Jellyfish lands on it's mother. Squidward torches the Jellyfish by hitting it on it's mother but karma comes to him. Squidward runs away as the mother tries to zap him hard. Eventually he does get zapped by the jellyfish.
The next day SpongeBob and Patrick enter with plasters all over themselves. Squidward arrives who's only wish is to enter his house. The two try to apologize but Squidward gets his revenge by opening a jar with a Jellyfish inside as a gift from SpongeBob. They run off as they get stung. Squidward is laughing until the mother returns to zap him once more.
