The girls receive an invitation to the wedding of Mojo Jojo and Barbarus Bikini. Bianca Bikini shows up and asks for the girls' help in stopping the wedding under the presumption of evil doings (of which Blossom and Buttercup agree). When Barbarus finds out that Bianca was trying to break up the wedding, she goes on a rampage after Bianca.
This episode contains examples of:
- Arson, Murder, and Jaywalking: From Bianca:They're going to do something evil at the wedding, but you didn't hear it from me! The wedding starts in five minutes! The colors are chartreuse and goldenrod.
- Bridezilla: As indicated by the episode title, Barbarus. However, she only gets upset when Bianca objects to her marriage to Mojo.
- Hypocritical Humor: Buttercup wigs out when first Mojo blasts through the house's façade and then Bianca follows suit. And after all the times the girls did the same to villains' lairs.
- My Eyes Are Leaking: When Barbarus and Bianca reconcile, Buttercup is seen crying. ("I'm not crying! I'm just allergic to sad stuff!")
- Stock Aesop: Two, from Bubbles: "You can't judge a villain by its cover," and "It's better to have loved and lost than to have never loved at all."
- There Was a Door: Both Mojo and Bianca break into the Utonium home without using the door. Buttercup Hangs A Lampshade on it.
- Unable to Support a Wife: Mojo, and only because he and Barbarus suddenly had conflicts of interests before they took their vows (he likes coffee and hates tea, she likes tea and hates coffee, etc.).
- Wedding Smashers: Blossom and Buttercup attack Mojo and Barbarus' wedding in the belief that it's really a ploy to gather everyone in town to blow them up with a bomb. (Bubbles doesn't join in the attack as her expertise on affairs of the heart tell her that Mojo and Barbarus are quite sincere in their love.)
