All There in the Script: The Lenopans are never called by their proper species name. At most, Grandpa Max can only offer the info that the Plumbers refer to them as "sludge-puppies".
Altar Diplomacy: Played With. Camille and Joel want to get married because they genuinely love each other. Their marriage ending the feud between their races is just a nice little bonus.
Amazon Chaser: When Camille turns into her Lenopan form to fight her disruptive family, Joel says admiringly to himself, "She is going to be my wife".
Bitch in Sheep's Clothing: For most of the episode Camille's parents act supportive (or at least non-obstructive) of the couples while showing annoyance at the judgmental attitude of Joel's parents. Then it turns out Camille's parents are far more judgmental themselves and are the ones trying to stop the wedding.
Body Horror: Gwen is pretty freaked out when one of the Lenopan guests approaches her, slightly vivisected and disfigured.
Bridezilla: Reconstructed, as Camille weaponizes her anger towards her family for actively ruining her wedding.
Dramatic Irony: Camille’s parents, annoyed at Heatblast, state that he must come from the groom’s side of the family, unaware that he is in fact said groom’s second cousin.
Easily Forgiven: Camille is one to forgive her in-laws for being suspicious of her.
Exact Words: Joel forbids his parents from carrying anymore weapons for the rest of the wedding. When Camille's parents begin disrupting the wedding, they lament not having their weapons, only for Max to give them weapons, stating that he made no such promise.
Fantastic Slur: Joel's parents and most Plumbers refer to Lenopans as "sludge-puppies" or simply "sludges", though these terms are not revealed to be slurs until Omniverse.
Feuding Families: More like feuding races. The Plumbers and the Lenopans have been at each other's throats for many years, right up until the pact between them was formed.
A Form You Are Comfortable With: Camille's human form is a lovely red-headed woman. Her "true" form is a humanoid mud alien. Her true-true form is a mud-blob alien with wriggling whiskers. Of the three forms, she's often seen in the former two.
Good-Times Montage: The ending of the episode shows a montage of all sorts of happy (and comical) memories being made at Camille and Joel's wedding.
I Can't Dance: Ben may not show it, but he's self-conscious that he's never danced before. Gwen eventually teaches him how to dance, with very mixed results.
I Lied: When Camille's parents attack everyone Joel expresses surprise since they said they liked him. This is the response Camille's dad gives.
Logical Weakness: Lenopans, being made out of a mud/sludge-like substance, can dissolve if they get submerged in a body of water, as shown when Camille's ex-boyfriend ended up in the hot tub. Intense heat can also dry them out and solidify them into a brittle mass, which made Heatblast the perfect alien to fight Camille's parents.
Love Across Battlelines: During a battle between the Lenopans and the Plumbers, Camille and Joel bumped into each other and almost instantly fell in love with each other. A peace treaty was formed from their relationship.
The Man Behind the Man: Camille's parents were bent on sabotaging the wedding from the start. Camille's ex-boyfriend was just a pawn in their game.
Noble Bigot: In addition to the animosity shown to Lenopans, Joel's parents immediately assume that Ben (as Cannonbolt) is trying to sabotage the wedding, while they have weapons trained on him, and refuse to hear him, or Max who tries to defend Ben, out. While they weren't necessarily wrong to be distrustful of Camille's parents, they do acknowledge that they were unfair to Camille herself and apologize.
Perpetual Smiler: One hardly ever sees Lucy with anything but a sunny smile. The only exception is when she's fleeing the wedding in the face of Camille's parents getting aggressive.
The Pollyanna: Lucy. Never mind that she hails from an alien race of mud creatures. She's a cheery ball of sunshine who's happy and excited about everything, and always has a smile on her face.
Properly Paranoid: Throughout the episode, Joel's parents are suspicious of Camille's parents, despite them acting friendly and supportive. Their suspicions are justified when it is revealed they are the ones behind the sabotage for the wedding.
Psycho Ex-Girlfriend: Gender-reversed example; Camille has one, and he doesn't take it too well when he learns she's getting married.
Retired Badass: Like Max, Joel's parents are retired Plumbers who still carry around their weapons.
Troll: When Ben finally dances with Lucy, he does well... and then Lucy turns her feet back into mud, causing Ben to slip and fall, and laughs hysterically.
Wedding Episode: The episode takes place roughly around Ben's cousin Joel's wedding. Hijinks ensues as wedding crashers in a form of mud-like aliens called Lenopans, which includes the bride's parents, wants to disrupt the wedding due to a long-time feud with the Plumbers.
