"High Sea Diving" is a SpongeBob SquarePants episode from season 11. In this episode, SpongeBob wants to be the first sponge to dive all the way up to the surface of the ocean.



The episode begins at SpongeBob's house, where we see a crowd of people gathering outside. Perch Perkins is reporting on the news that SpongeBob is attempting to dive to the surface of the ocean, and he will be the first sea sponge ever to do so. Inside SpongeBob's house, Gary is rubbing lard on SpongeBob's back, as SpongeBob fantasizes about the upcoming event. In the fantasy, a little kid walks up to a SpongeBob statue, who talks to him. The little kid screams and runs away as the fantasy sequence ends, and SpongeBob claims that he has to warm up. SpongeBob attempts to lift some weights, but ends up accidentally throwing the weights out of his house, and exclaims that he is ready. Back outside, Mr. Krabs is seen selling SpongeBob standees. Patrick walks up to one of the standees (thinking that it is the real SpongeBob), and tries to make conversation with it. Patrick thinks SpongeBob is giving him the silent treatment, prompting him to do the same. Bubble Bass, thinking Patrick is a standee, walks up to Mr. Krabs and asks him how much he is worth. Bubble Bass ends up paying 10 dollars for the "standee." SpongeBob then walks out of his house and attempts to do the high sea dive off of an upside down diving board, only to fail, disappointing the crowd of people as they walk away.

SpongeBob questions why he was not able to go up, to which Sandy walks up to him and tells him that Olympic divers in Texas use gravity to help them go down, and that he should use anti-gravity to go up. As Sandy walks away, SpongeBob gets an idea and runs inside of his house. He then returns to the upside down diving board, now with balloons tied to his waist, and dives to the surface of the ocean, while Squidward is seen in the background grumbling to himself and picking up trash. As SpongeBob is about to reach the surface of the ocean, he is blocked by a giant island of trash from the surface world, which also causes his balloons to pop. SpongeBob is upset about this at first, but decides to explore the trash island. He plays with a giant telephone and a giant comb, and accidentally runs into a giant building. This causes the objects, as well as a couple of others, to float down to the bottom of the ocean. Just then, a group of fish look on as a farmer uses the giant comb to grow his crops, making the fish assume that these are gifts from Neptune. Nearby, a group of campers use a giant pen to hold up their tent, and a recently married couple use the giant building as a house.

Meanwhile, SpongeBob continues to explore the trash island, but out of nowhere, he is hit in the face by a giant fork. The thrower is none other than Old Man Jenkins, who has gone crazy and thinks he is King Neptune. SpongeBob plays along, claiming to be Poseidon. SpongeBob and Old Man Jenkins then start throwing random giant objects at each other, causing them to float down to the bottom of the ocean. Back in Bikini Bottom, one fish uses a giant knife as a surfboard, and a couple of other fish use a giant vacuum cleaner as a car. A little girl is seen attracting a crowd of people, and excitedly tells them that if they want to receive something from Neptune, they will have to send him messages using balloons, and the crowd does exactly that. Up on the trash island, Old Man Jenkins examines SpongeBob, and discovers that he is not actually Poseidon, to which SpongeBob points out that Old Man Jenkins is not Neptune either. Old Man Jenkins explains his backstory on how he ended up on the trash island. One year ago, we see Old Man Jenkins celebrating his birthday party. A fat woman gives Old Man Jenkins about a dozen balloons, causing him to float upward. The old people seem to be apathetic to the situation, and walk back inside. As the flashback ends, a bunch of balloons are seen landing on the island, with different people saying what they want from King Neptune.

Old Man Jenkins wants to go back down to Bikini Bottom to help his "subjects," and SpongeBob gets the idea to build a ladder out of the trash to climb back down. Meanwhile, the Bikini Bottomites are freaking out because no more trash is coming down from the surface. As they are about to sacrifice a woman fish, the ladder that SpongeBob and Old Man Jenkins built reaches the ground. Everyone thinks that if they climb the ladder, it will lead them to more free stuff. On the surface, SpongeBob finishes building the ladder, as he notices that they are right at the surface. He proudly plants a flag on top of the ocean, and the both of them start climbing down the ladder. They notice that the ladder is shaking, and the Bikini Bottomites see Old Man Jenkins, thinking that he is Neptune. This makes everyone shake the ladder even harder, but SpongeBob explains that he dove up to the surface of the ocean and found Old Man Jenkins living among the objects. The people exclaim that SpongeBob is the one that sent down the objects and call him a hero. The ladder ends up shaking so much that it completely collapses and spreads trash throughout Bikini Bottom. Old Man Jenkins surfaces out of the trash, still claiming to be King Neptune. Suddenly, the real King Neptune shows up, and smites Old Man Jenkins with his trident. Mr. Krabs approaches the massive trash pile and pulls a flattened SpongeBob out of it. He thinks SpongeBob is another one of his standees and throws him in the back of his truck and drives off. SpongeBob reflects on how the citizens of Bikini Bottom called him a hero, as the episode ends.


The episode was confirmed by Vincent Waller on December 31, 2017.[2]
