135a - Back to the Past
SpongeBob and Patrick are strolling through Bikini Bottom and see Mermaid Man and Barnacle Boy in the Invisible Boat Mobile, without gas. SpongeBob and Patrick push the boat over several hills.
Barnacle Boy invites them into their warehouse full of memorabilia from their T.V. show. Barnacle Boy shows them a time machine which they have never used, and warns them not to use it.
But Patrick mistakes it for a vending machine, and all of them are transported to 1954 when Mermaid Man and Barnacle Boy are young. They see Man Ray tormenting old Bikini Bottom. Mermaid Man and Barnacle Boy are unsuccessful at foiling Man Ray due to Patrick eating the tartar sauce they were originally going to trap him in.
SpongeBob and Patrick escape old Bikini Bottom, leaving their Mermaid Man and Barnacle Boy behind. When SpongeBob and Patrick return to Bikini Bottom, it is no longer called Bikini Bottom, but Man Rayopolis. They go to the Krusty Krab which now has no name.
The superheroes from their time are now dead and buried inside of the restaurant while the past superheroes now work there. Mermaid Man is the fry cook, SpongeBob's position, and Barnacle Boy is the cashier, Squidward's position. They go back to stop Patrick from eating the tartar sauce, but the heroes who were sent by accident believe they are impostors. The Mermaid Men fight which creates the perfect distraction for Man Ray. The young Mermaid Man and Barnacle Boy attempt to foil Man Ray with the tartar sauce, but the two Patricks end up eating it. Another warehouse appears.
SpongeBob and Patrick from a different time period emerge from the warehouse screaming "Patrick, don't eat the tartar sauce!" Another warehouse appears above of Man Ray and out fall SpongeBob and Patrick. Yet another one appears with SpongeBob saying to Patrick "I told you we had to go back further!"
Another one pops to Man Ray's left with Mermaid Man and Barnacle Boy leaping out of it exclaiming, "Up, up and away!" They both fall headfirst into the ground. Another one appears above of the previous warehouse with the superheroes. SpongeBob and Patrick appear and throw a batch of tartar sauce over the fallen superheroes from the previous warehouse.
Another one appears next to the pair of warehouses. Man Ray flies out of it, destroys it, says, "I took care of your blasted time machine!" and leaves. All of the warehouses appearing in random locations confuses Man Ray. Man Ray sits down on a log and thinks about what is happening, but gets arrested by the superheroes. Then all of a sudden, many warehouses appear all over the planet, all of them containing multiple copies of SpongeBob and Patrick.
