- An Aesop: You don't have to imitate others for the sake of it, just be yourself.

- Gone Horribly Right: SpongeBob starts imitating everyone so much he develops "Mocking Mimicry Madness", causing him to forget who he really is.
- Here We Go Again!: In the end, after SpongeBob's friends pretend to be him to return him to normal, they end up getting Mocking Mimicry Madness themselves to his horror, though he joins in anyway.
- Identity Amnesia: Doing so many imitations of everyone causes SpongeBob to forget who he really is.
- Melancholy Musical Number: SpongeBob has one as he succumbs to Mocking Mimicry Madness and begins to lose his true identity.
- Pet the Dog: Patrick threatens Squidward and Plankton with violence after they suggest killing SpongeBob.
- Shapeshifter Identity Crisis: SpongeBob performs so many impressions of other people that he ends up developing a condition called "Mocking Mimicry Madness," forgetting who he really is.
- Shapeshifter Mashup: Patrick, Squidward, Sandy, Mr. Krabs and Plankton all show up at SpongeBob's house for an intervention. In response, SpongeBob decides to imitate all five of them at once, much to everyone's horror.Patrick: WHY?!
When worms move in to SpongeBob's holes, it's up to him to hide his disgusting new friends from everyone else.
House Worming contains examples of:
- Animal Jingoism: Like in "Pet or Pests", Gary hates the worms that occupy SpongeBob's body, to the point of kicking SpongeBob out of his own house until he gets rid of them.
- Annoying Laugh: The thing that finally drives the worms away from SpongeBob is the sound of his laughter.
- Here We Go Again!: At the end, the worms invade Squidward's house.
- How We Got Here: The epilogue "Clam Up" shows how Prickles the worm ended up at SpongeBob's house.
- Laughing Mad: SpongeBob as part of his Sanity Slippage.
- Nightmare Face: The worms form one on SpongeBob's face to scare his friends away from him.
- Sanity Slippage: SpongeBob has one when he believes he'll have to spend the rest of his life as an apartment for worms.
- Taking Advantage of Generosity: After SpongeBob allows Prickles to stay in his body, Prickles's next action is to invite all his friends to stay in SpongeBob's body and spend the whole night having a loud flashy dance party.
