The episode opens on Spongebob, Patrick, Squidward and Triton's houses (Triton moved from his dad's kingdom and now lives in an RV next to Spongebob's house). Triton's alarm clock sets off, along with Spongebob's and Patrick's. They all head for the Krusty Krab. While Triton and Patrick eat Krabby Patties, they hear Spongebob scream. They head to the freezer where they discover that the Krusty Krab has just ran out of patties. However, Plankton arrives and steals the formula. Mr. Krabs grabs him by a magnet and tells Spongebob, Patrick and Triton that's he's hiding the formula on the other side of the ocean. They get back to making to making the Krabby Patties.

They forgot to look at the formula. Spongebob asks Mr. Krabs if he, Patrick, Triton and Mindy can go find it. Mr. Krabs gives them the key to the formula.

They head to the train station where they are given tickets for the Oceanic Express (while Triton explained that he always wanted to go on "The Galactinic Express"). They go onboard as the train starts.

They enter their room, but it soon becomes night and they all fall asleep except Triton, who sees the Northern Sealights, "Aurora Borealis". Then he exits his room to search the train for clues. He encounters the conductor's quarters and notices, in his closet, there's a medallion lost on the train. Anyone who finds it will be able to guide all of U.S.A.'s residents to Atlantis: the real version! Triton looks at his watch and realizes that it is 12:00am Midnight. Triton searches everyone's cabin for the medallion until he stumbles upon the train locomotive. There, on the whistle cord, is the medallion. He snatches it, and returns to his cabin before sunrise.
