Upset over Mr. Robinson putting his house up for sale and preparing to move away, Gumball and Darwin decide to make their final moments with their grouchy neighbor last. When that doesn't work, the duo decide to sabotage the sale.
Tropes
- Bowdlerise: In the European Spanish and Polish dubs of this episode, the part where Gumball dresses as a creepy hick who warns the potential buyers to stay away from the house was edited to remove Gumball trying and failing at doing a Spiteful Spit
because it's considered far more offensive there. - Continuity Nod: The wolf mask Gumball and Darwin put on Richard while he sleeps is the same one Richard wore on "The Vacation" in the flashback of how Nicole's day off on Halloween was ruined.
- Depth Deception: Darwin uses a highly-detailed chalk drawing to make it look like there's a Hellgate on the road in front of the Robinson house.
- Failed Attempt at Drama: Gumball's attempt as a harbinger below fails because he makes a declaration that make no sense because he refers to bringing them there when he didn't, fails to punctuate it with a Spiteful Spit because the loogie won't break off, and fails a Vehicle Vanish when they spot him hiding behind the trash can.
- Harbinger of Impending Doom: Gumball puts on a creepy hick getup and tries to play the part to the Bensons when they arrive at the Robinson house.
- Haunted House: Gumball and Darwin try to give the Robinson house this vibe to scare the Bensons off, sorta like short-term "Scooby-Doo" Hoax.
- Insulted Awake: Gumball and Darwin are initially in a state of malaise over the Robinsons moving, but immediately return to reality infuriated when Nicole suggests that they might get some pleasant neighbors once the Robinsons are gone.
- Jump Scare: Darwin attempts a sudden scare when pretending to be a ghost, but he gets a door slammed in his face as he rushes forward and falls through a window.
- Mondegreen Gag: When Mr. Benson says "their soil" Gumball mishears it as "there's oil".
- Multitasked Conversation: When Mr. Robinson is on the phone with one potential buyer, Darwin and Gumball keep pestering him. Mr. Robinson's angered yelling toward them are misinterpreted as being toward the caller, who hangs up.
- Nightmare Face: Gumball and Darwin manage to intimidate Nicole with this when she slights Mr. Robinson.
- Plant Person: The would-be buyers of Mr. Robinson's house turns out to be Mr. Benson, the previously seen walking corn stalk, and his newly introduced wife the walking mushroom. They only want Mr. Robinson's house because his soil is perfect for planting their children.
- Police Brutality: Darwin takes his "brutal cop taking in a career criminal" role a bit too far. Mrs. Benson finds him scarier than the criminals and afterwards Gumball is nursing a persistent Cranial Eruption.
- Sinister Silhouettes: Darwin appears as one to Mrs. Benson, at the end of the hallway and only visible when the light is off, stalking her when she's not looking as a part of their Haunted House routine.
- Stalker Shrine: Gumball and Darwin have had one for Mr. Robinson for quite some time that the family have never noticed until the episode.
- Stalker without a Crush: Gumball and Darwin are revealed to have had a shrine to Mr. Robinson in their living room for a long time. When they find out he's moving, they ask if they can take out one of his threads and eat it so he'll "be a part of [them] forever". Why they love him so much is anyone's guess.
- Stringy-Haired Ghost Girl: Darwin takes on the appearance and mannerisms in Robinson's bathroom as an attempt to scare Mrs. Benson.
- Sudden Anatomy: Darwin swears a vow of silence in honor of Mr. Robinson moving away, so he suddenly has rotoscoped hands with five fingers that sign to Gumball why he's not talking.
- Take That!:
- While using a keyboard to make unpleasant sounds to suggest unfavorable landmarks, the boys accidentally play a track of farts. The Bensons assume it means the neighborhood has vegetarians.
- The magazine Margaret reads while Mr. Robinson is showing his house to potential buyers is called Your House Will Never Be Good Enough, a scathing spoof of home and garden magazines advertising a type of unattainable perfection that people strive to emulate.
- Darwin apologizes to Gumball for taking his police officer role too far, citing "an unchecked sense of authority."
- With a Foot on the Bus: The Robinsons attempt to move, going as close as having the paperwork ready for the final signature, but Gumball stops the signature and seemingly proves the land had oil. The "oil" was really just raw sewage, but Darwin and Gumball apparently drive off the last potential buyers in disgust, so the Robinsons are stuck where they are anyway.
