"Sunken" (stylized as SUNKEN) is the 312th episode of SML Movies.
The video starts with Junior, Cody, and Joseph sitting on the red couch. Junior asks what they want to do, and Cody says they are going whale watching because he won 5 tickets for it and that he has been waiting to say so all day. Junior, jokes about them watching Cody's Mom and Joseph calls him Savage. Cody is pissed and corrects Junior saying he means 'whales in the water' and Junior questions why they would watch Cody's Mom taking a bath and Joseph calls him Savage a second time. Finally, Junior and Joseph agree to go with Cody to go whale watching and Chef Pee Pee goes with them.
On the Boat, Brooklyn T Guy says there's gonna be tons of whales, maybe even the great Moby . Junior thinks he's trying to molest him so he tells Chef Pee Pee and Brooklyn T Guy tells him he means the one from the books. They move onto watching for whales. They keep thinking a whale is going to come out of the water, but it's just a wave. Junior and friends get bored and give up watching for whales.
Cody asks Ken while he's naked if them together on a boat is romantic. Junior complains about the trip being lame, but Joseph says he kinda likes it because he has never been on a boat before. Junior asks Cody why Ken is naked. He answers with that he likes skinny dipping and likes the way the wind feels on his crotch plate. Joseph complains about him being a doll!
Junior throws Ken off the boat and deep into the ocean, distracting Cody who announces that a 'Hunky Man' has gone 'Overboard'. Junior tells Brooklyn T Guy about the situation and he tells him that they're above shark-infested waters and says he lost his wallet down in the same ocean, meaning he lost his credit cards and Driver's License. He says they could take his submarine to get Ken. He trusts them because they look like nice people. Cody and Junior go down in the submarine while on it they see weird stuff as a peanut Butterfish and a toast fish.
They find a Button that can talk to fish they use it to ask for directions but the fish is shot by a killer whale. They then get lost after escaping a shark with a pool table. They hit the sea floor and stop a red lobster restaurant Cody goes and ask directions and grab some biscuits. Afterward, they see more weird stuff as a "star" fish. They find a shipwreck and see treasure. Junior wants to get it but Cody says no because of the mines.
Ken is eventually spotted in a fish's mouth and bites him as Junior and Cody try to get it back they get half of it and drive off. Junior drives to the shipwreck and tries to get the treasure he successfully avoids the mines and gets the treasure but heads straight into the mines and explodes the submarine. Cody and Junior come back to see the whale who is Cody's mom, much to Cody’s annoyance.
