The dumpster is a waste container that is usually featured behind the Krusty Krab. It first appears in the episode "Graveyard Shift."
The dumpster is normally light gray, yellowish-brown, with brown rust markings and green goo stains, and filled with garbage bags like a dumpster usually is. It is normally located behind the Krusty Krab.
In "Sailor Mouth," the dumpster is featured with graffiti on it.
SpongeBob goes out with the trash around closing time to throw it in the dumpster. He then looks at the dumpster writing, looking at the words, then he finds the following words: "Krabs is a [dolphin chirp]," learning the nature of profanity.
SpongeBob and Patrick go search for SpongeBob's name tag. Patrick attempts to help SpongeBob dig up the garbage to find it, before Patrick eventually notices SpongeBob was wearing his shirt on backwards.
SpongeBob puts a trash bag in the dumpster, but Plankton pops out of the bag with a Krabby Patty. He runs off, but the Krabby Patty explodes. Mr. Krabs explains that all Krabby Patties explode within five feet of the Krusty Krab.
SpongeBob goes out to dump the trash in the dumpster. While he throws away the trash, he finds a book and remarks how they should not be thrown away. Then a slimy trash monster emerges from the dumpster. SpongeBob throws the book at the monster, only revealing them to be Sandy.
SpongeBob delivers an order to the dumpster and states that Squidward must have received a prank call. He leaves the order on top of the dumpster. Patrick pops out and finds a ketchup packet inside the bag and says that it will go great on an old diaper that he found.
SpongeBob hides in the dumpster from the Krabby Patty creatures. Perch Perkins walks past, delivering a news report. When mutated Squidward grabs him, he quickly tells SpongeBob that Plankton was never affected by the creatures, and SpongeBob bolts out of the dumpster and to the Chum Bucket.
