2	Fern finally has his fatal mental breakdown, and sets out to replace Finn.
3	----
4	!!Tropes:
5	* AccidentalMurder: Finn ''didn't'' want to kill Fern; his robotic arm mistook him saying "finality" for "fatality" and put the weed-whacker function into overdrive.
6	* BareHandedPuppetry: In the introduction video for the mechanical arm, Princess Bubblegum amuses Finn with a puppet.
7	* {{Beat}}: After Finn tells Fern he's like a brother, or maybe even closer, Fern stares at him for a good long while before telling him to walk into the trap.
8	* BrickJoke: Jake goes to buy a new vuvuzela because BMO broke his old one. When Finn comes back, you can see BMO trying to break Jake's new vuvuzela.
9	* CallBack: The prison Fern traps Finn in is a near-replica of the inside of the Finn sword.
10	** The fight scene mirrors the creation of [[Recap/AdventureTimeS6E19IsThatYou the creation of the Finn Sword]], the way Finn sneaks up on Fern while screaming and "kills" him. Doubles as foreshadowing for Fern surviving the attack, and metaphorically becoming Gumbald's sword.
11	* DissonantSerenity: BMO cheerfully replies that he guessed that Finn killed Fern.
12	* DontMakeMeDestroyYou: Finn really doesn't want to kill Fern, but since Fern is beyond hope he has no choice.
13	* DownerEnding: Fern undergoes a FaceHeelTurn and almost immediately [[LaserGuidedKarma pays dearly for it]], while Finn has a HeroicBSOD over destroying most of Fern by accident.
14	* FaceHeelTurn: Fern, stewing over his recent failures, decides ThereCanBeOnlyOne and turns on Finn.
15	* {{Foreshadowing}}: The fight scene mirrors the creation of the creation of the Finn Sword from "[[Recap/AdventureTimeS6E19IsThatYou Is That You?]]", foreshadowing Fern surviving the attack, and metaphorically becoming Gumbald's sword.
16	* GoodEyesEvilEyes: Fern gets the same eyes as the Grass Sword curse creature after he decides to replace Finn.
17	* IAmSpartacus: After BMO confesses to breaking Jake's vuvuzela, NEPTR also claims he broke it, possibly for attention. Fern (while pretending to be Finn) quickly joins in.
18	* JustifiedTitle: The title refers to the bucket of trash in Fern's prison, the bucket in Finn's backpack, and the bucket the mysterious figure used to collect Fern's remains.
19	* KillAndReplace: Fern decides to replace Finn, though instead of killing him he wanted to secretly keep him prisoner. However, Fern is such in inept jailer that Finn would have likely starved to death if he hadn't managed to escape.
20	* MyGodWhatHaveIDone: Finn after he accidentally kills Fern.
21	* NewPowersAsThePlotDemands: Justified, Finn's prosthetic arm has dozens of different attachments. Finn just never noticed because there was ketchup on the microphone. And because, well, [[IdiotHero he's Finn.]]
22	* RockPaperScissors: Finn and Fern play it on their way to the ruins. Fern is upset that they keep tying, but [[SoreLoser he gets even more upset when he loses]].
23	* SequelHook: Fern's sentient remains are picked up by some mysterious figure, later confirmed to be Princess Bubblegum's Great-Uncle Gumbald.
24	* ThousandYardStare: Finn doesn't come out of killing Fern well.
25	-->'''BMO''': [[NoodleIncident I know that look]], you just killed someone.
26	* TwinSwitch: Using his newfound ShapeShifter abilities, Fern is able to pass himself off as Finn. The first time was a joke between him and Finn, but then it turns serious when Fern traps Finn so he can take over his life.
