Ocean of Fear

Ocean of Fear is episode number sixteen in season one of Adventure Time with Finn and Jake.

Synopsis
Finn discovers he's scared of the ocean, so he enlists Jake's help to overcome his fear but ends up failing.

Plot
Finn and Jake chase a Fire Newt after he steals boots, similar to what Jake did in City of Thieves. When Jake decides to fight the Newt by farting on it, Jake chases it into the ocean, but when Finn tries to catch up with Jake, Finn backs up from the waves and freaks out. Suddenly, his stomach gurgles and out comes a dark, evil cloud who explains he is the manifestation of Finn's ocean fear and tells him that he can never be a hero if he cannot overcome his fear. After the Fire Newt is defeated, Jake goes back on land and Finn tells that he thinks he is afraid of the ocean and wants Jake's help to overcome his fear. Jake decides to help and comes up with a three-step plan to help Finn with his fear. When Jake moves Finn's feet to help him get into the ocean, Finn jumps on Jake's head and yells at him to bring back on land. Jake decides to resume it tomorrow. Finn wants to restart now, but overreacts over one tiny drop from one of the waves, and Finn agrees on Jake's decision.

The next day, Jake wakes Finn up and reveals that he moved Finn's room into the ocean. As Finn begins to overreact, Jake reveals he has contained Finn by trapping him in his sleeping bag. Finn tries to calm down, but when Jake dunks Finn's head into the ocean, Finn finally breaks free and jumps on Jake, then beats him up. Finn uses Jake's ears as sails to get to a cliff, and Jake decides to give up, as he is sick of Finn always beating him up whenever he goes nuts. Jake decides to help Finn one more time, but makes Finn promise not to beat him up anymore and speaking in rhymes. Jake brings a submarine and he and Finn both go in it. Finn sees the true beauty of the ocean, but when Jake tries to dive in to a black abyss, Finn breaks his promise, overreacts, beats Jake up again, and makes leaks onto the submarine when trying to bring it back up to shore. Finn finally overreacts and as he puts on his diving suit and pulls the emergency cord, making him float up back to the top of the ocean, but Jake gets unconscious from the incident and sinks to the bottom. Fear Feaster arrives and tells Finn that he can't overcome his fear now that Jake is going to die. Since Finn can't handle being in the ocean awake, Finn knocks himself out and sinks to the bottom of the ocean, dragging Fear Feaster with him.

Finn reaches the bottom and wakes up after shrimp clink on his helmet, and when he wakes Jake up, Jake tells Finn they are at the bottom of the ocean. Finn screams and tries to pull his emergency cord to get back up, but can't and Jake decides to pull his to help him and Finn get back on land. Jake congratulates Finn on conquering his fear, but Fear Feaster shows up again and tells Finn he will never be a hero if he is scared of the ocean. Suddenly,   A limo appears and three wise men come out of it, telling Finn that Fear Feaster is wrong and he truly is a hero. The Wise Men and Fear Feaster go back inside Finn and he and Jake celebrate over Finn's victory.

Trivia

 * The episode was originally titled "Finn Underwater."
 * The quotations at the beginning and end of the episode are credited to "Pat McHale." Patrick McHale is Adventure Time's Creative Director. The quotations are narrated by Clancy Brown.
 * On the ocean floor are the remains of a city. The remains of forgotten cars, buildings, and even people are most likely further evidence of the Land of Ooo's post-apocalyptic setting. A destroyed tank and sunken aircraft carrier further prove the post-destructive war.
 * When Finn sinks to the bottom, small pink Shrimp appear to be living there, despite Ooo's apocalypse.
 * In only the scenes where Finn and Jake are above water, there seems to be giant mounts of sand in the background. This may be the Spikey Village.
