Gumball: Why are you so angry I had a best friend before you?
When Gumball's old BFF turns up, Darwin gets jealous.
Tropes:
- Bittersweet Ending: Gumball and Darwin stop Fuzzy. But they are still stranded in the middle of the woods — hundreds of miles away from home.
- Breather Episode: A relatively mellow episode with a Minimalist Cast, right before the Series Finale.
- Eviler than Thou: Hank turns out to be an even bigger Yandere towards Fuzzy than Fuzzy was towards Gumball.
- Expy: Hank is a walking Tamagotchi creature who seems to resemble Kuchipatchi specifically.
- Faux Furby: Fuzzy is lampshaded by Darwin as an expy to Furbys.
- Old Friend: As it turns out, before Darwin came along, Gumball (in his very early childhood) had a "BFF" named Fuzzy (who eventually moved to Minnesota).
- Minimalist Cast: Only six characters make an appearance here, the lowest amount out of every episode and even then, Gumball, Darwin, and Fuzzy are the only prominent characters.
- Passive-Aggressive Kombat: Darwin keeps using euphemisms like "fascinating" and "interested" for his unfounded suspicions of Fuzzy and Gumball keeps calling him out and demanding he say what he means outright.
- Refuse to Rescue the Disliked: Darwin and Gumball consider saving Fuzzy from Hank but decide it's not worth the effort when they're already so far away from home.
- Robotic Reveal: Unremarked upon by the characters but it seemed at first that Fuzzy was a living creature that happened to resemble a toy but, when Darwin strikes him over the head with a shovel, he ends up two-faced not unlike a Terminator.
- Sequel Episode: Of sorts to “The Bros,” as both episodes deal with Darwin becoming irrationally jealous, stemming from his fear that Gumball may eventually abandon him for someone else.
- Subverted Suspicion Aesop: Despite Darwin's jealousy and suspicions being essentially baseless, Fuzzy really is trying to kidnap Gumball.
- Yandere: Fuzzy turns out to be one for Gumball.
- While "The Bros" shows that Darwin can be a touch too clingy towards Gumball, this episode shows him at his most possessive.
