SpongeBob decides to abandon his normal ways and live with the jellyfish. Patrick does not take this well.
Nature Pants provides examples of:
- All of the Other Reindeer: For obvious reason. Spongebob is shunned and zapped out of Jellyfish Fields because he is CLEARLY not a jellyfish.
- An Aesop:
- You can't become something you're not just by acting like it. You are what you are and you should accept it.
- Dont make life-changing decisions without thinking of the consequences.
- Ax-Crazy: Patrick, of all people, goes crazy when SpongeBob refuses to come home. He even threatens to put SpongeBob in a jar and keep him in there. Forever.
- Bad "Bad Acting": Patrick in the scene below.
- Barbie Doll Anatomy: On SpongeBob, after he goes and lives with the jellyfish.
- Break the Cutie: Patrick does not take SpongeBob leaving well.
- Brick Joke: The poison sea-urchins.
- Epic Fail: Instead of using the fire extinguisher to put out the fire from the grill, SpongeBob simply throws it right at it.
- Hulk Speak: Patrick devolves to doing this during his breakdown.
- Inelegant Blubbering: Patrick while SpongeBob is giving his stuff away and leaving. He is on the verge of losing his best friend after all.
- Ironic Echo Cut: "Even Squidward misses you." Cut to Squidward throwing himself a "Goodbye, SpongeBob" party.
- My God, What Have I Done?: When SpongeBob realizes the error of abandoning his normal ways.
- Nature Lover: What drives SpongeBob to live with the jellyfish.
- Noodle Incident: "That's the fifth time this week I had to scrape you off of something."
- Offscreen Crash: Patrick causes this when he throws aside the pile of SpongeBob's old phone books.
- Ominous Music Box Tune: When Patrick declares that he's going to make SpongeBob a trophy.
- Painting the Fourth Wall: Squidward references the episode's running time:Sandy: I give him a week.
Squidward: I give him eleven minutes.
- Please Put Some Clothes On: Squidward, when he gives SpongeBob his pants back at the end of the episode.
- Reading the Stage Directions Out Loud: Patrick, in this scene:
- Reality Ensues:
- SpongeBob's Imagine Spot causes him to neglect his on-the-job duties as a fry-cook. Cue the patties he's cooking being burned due to him ignoring them to daydream. Also they go on fire for some reason.
- SpongeBob tries living amongst the jellyfish as one of them, but it all goes wrong. He's not a jellyfish, so they reject him. Offering one a handshake causes its tenticle to sting him. Hiding in a jellyfish hive just makes them sting him some more and drive him away. He tries sleeping in a cave, and is covered in poisonous sea urchins. Nature Is Not Nice and anyone who fails to realise that will have a bad time in the wild.
- The group hug at the end results in the others getting the itchy poison from those sea urchins because it wasn't that long ago that SpongeBob got stung by them.
- Scenery Censor: When SpongeBob takes off his pants, he's standing behind a bush. Scenery censors are used at multiple other points as well. Played with, as the episode shows at other times that there's nothing to actually censor.
- Sea Hurtchin: After Spongebob gets zapped by jellyfish, he tries to call it a night by resting in a cave, all while bearing the cold with only a kelp blanket to barely cover him. All of a sudden, he gets a painfully itchy feeling, and it turns out that he's covered by poison sea urchins.
- Take This Job and Shove It: SpongeBob angrily quits his job at the Krusty Krab, throwing his hat onto the ground and storming out to start a new life.
- That Makes Me Feel Angry: "Patrick sad!" and later, "Patrick itchy!"
- What Happened to the Mouse?: The large rock Snail that wakes up and moves, forcing SpongeBob to find a new hiding spot. It has only appeared in this episode.
- Yandere: A rare platonic example. Patrick loses his damn fool mind after SpongeBob refuses to come back to civilisation, trying to cram his friend into a jar and keep him as a trophy.

Squidward tricks SpongeBob into believing it is opposite day, so he can try and move away from SpongeBob. Needless to say, this eventually backfires.
Opposite Day provides examples of:
- An Aesop: Don't make any attempts to goad someone into altering his/her traits. It can backfire and get the person to act even worse than what you intended.
- Bad Impressionists: Patrick when imitating Squidward. He just goes "I'm Squidward, I'm Squidward" over and over in his normal voice.
- Big "NEVER!":Squidward: (clinging to the real estate agent's leg) Please sell my house!
Real Estate Agent: (yanks her leg out of his grip) NEVER!
- Big "NO!": Squidward screams one when he sees the realtors boat parked outside his house.
- Bottle Episode: Most of the episode is set at SpongeBob's home lane.
- Butt-Monkey: Squidward, especially since he was trying really hard to sell his house in this episode.
- Celebration Miscalculation: The episode opens with SpongeBob and Patrick throwing Squidward a surprise birthday party. After they leave, Squidward yells: "It's not my BIRTHDAY!"
- Chased Off into the Sunset: In the ending, Squidward chases SpongeBob and Patrick with a bulldozer that he used earlier to clean up the mess they made at SpongeBob's house.
- Disproportionate Retribution: Squidward plans to move away from SpongeBob and Patrick - and to that end, tricks them into celebrating the made-up Opposite Day - because they threw him a birthday party. Compare this to "Squidville", where he successfully moves away from SpongeBob and Patrick for the more understandable reason that they destroyed his house.
- Getting Crap Past the Radar: In the German version, Squidward calls his neighbors "Barschgesichten" ("Perch faces"), a pun on "Arschgesichten" ("Ass faces").
- Holiday Episode: SpongeBob and Patrick celebrate the made-up holiday Opposite Day.
- I Will Show You X: When Patrick and SpongeBob tell Squidward, "Happy Opposite Day, Squidward! We hate you!", Squidward gets ticked off before suddenly smiling and calmly saying, "Let me show you how much I... HATE YOU!"
- I've Heard of That What Is It?: The Trope Namer:Patrick: Opposite Day? Hey, I've heard of that!
Patrick: No! What is it?
- Laser-Guided Karma: Squidward suffers this when SpongeBob and Patrick enjoying Opposite Day (the holiday he came up with in the first place) are what cause the realtor to cancel selling his house.
- No Name Given: The realtor is not named in the episode, nor is she named in the credits.
- Ocular Gushers: Patrick sheds them when he thinks SpongeBob is ending his friendship with him.
- One Steve Limit: Both averted (in-universe) and Played for Laughs.Real Estate Agent: He's Squidward, he's Squidward, you're Squidward, I'm Squidward! Are there any other "Squidwards" I should know about?!
Gary: (in Squidward voice) Meow.
Real Estate Agent: I'm outta here.
- O.O.C. Is Serious Business: Played with. SpongeBob becomes very concerned about Squidward's wellbeing when he sees him suddenly acting silly and cheerfully, but Squidward was just acting in order to convince SpongeBob that it's Opposite Day.
- Opposite Day: Obviously.
- Rage Breaking Point: The real estate woman when she gets introduced to the "third" (the real) Squidward.
- Rewind Gag: Part of their "oppositing" montage has SpongeBob and Patrick briefly speaking backwards.note
- Screw This, I'm Outta Here!: The Real Estate Agent, who's fed up with Squidward, SpongeBob, Patrick and Gary (pretending to be Squidward).
- Spanner in the Works: Squidward's plan to get SpongeBob to do nothing all day might have worked... if he had told Patrick about Opposite Day too.
- Status Quo Is God: With the realtor refusing to sell Squidward's house, he is to remain in Bikini Bottom between SpongeBob and Patrick to his dismay.
- Title Drop: Naturally.
