As Abuelita babysits Gretel, a villainess wearing many hats is terrorizing the city by draining their happiness; Abuelita recognizes her as La Sombrerona from folk tales. A carnival just so happens to be in town, so they, along with Fred, visit said carnival, knowing that La Sombrerona would make her next move there.
Tropes:
- Accidental Hero: When Kevin turn the pressure valve to win the game, he went flying due to the water pressure being too high, which he accidentally stops La Sombrerona by bumping into her while flying with the water hose.
- Art Shift: As Abuelita tells the tale of La Sombrerona, the visuals become more sketch-like with a limited color palette of sepia, black and white, inspired by woodcut illustrations of Latin American folk tales.
- Big Eater: After being effected by La Sombrerona, Hamster orders a dep fried cabbage with cheese on it.
- The Bus Came Back: This is Abuelita Gomez's second appearance and she is noticeably a little more mellowed out.
- Crusading Widow: La Sombrerona is a woman who married five times; every single one of her spouses preferred having fun over doing their job, and were promptly devoured by a tiger, so La Somrerona vows revenge against happiness in general.
- Hall of Mirrors: Hamster and Gretel confront La Sombrerona in a hall of mirrors and are unable to tell the real one from all the reflections. Gretel gets around this by lifting the roof, revealing the real Sombrerona. As she puts the roof down, all the mirrors shatter, prompting this comment from Hamster:Hamster: I can't even calculate how many years of bad luck that is.
- The Hilarity of Hats: La Sombrerona wears the hats of her five husbands stacked on top of each other. When they are removed, they reveal an antenna on her head, the source of her happiness-draining powers.
- Mama Bear: After seeing Gretel and Hamster crying due to La Sombrerona taking away their happiness, Abuelita Gomez steps into action and helps the villain be happy again with Fred's help.
- Misplaced Wildlife: In Abuelita's story, all of La Sombrerona's husbands were eaten by tigers, which Abuelita notes aren't native to Latin America, but were nevertheless abundant at the time. During the Hora Loca number, a tiger is visible in the background.
- No-Sell: Fred is immune to La Sombrerona's happiness-sucking rays. Can't sap away happiness from someone who's never happy, after all.
- Serious Business: Abuelita initially prohibits Gretel from going after La Sombreroba before she finishes her homework, but when La Sombrerona spreads misery at the shuffleboard court, then It's Personal.
- Shout-Out: La Sombrerona's name is similar to that of the Guatamalan legend and Mexican boogeyman, El Sombrerón
, who is notable for wearing an overly large hat. - Surprise Party: The gang decides to throw an Hora Loca for La Sombrerona in hopes it would cheer her up. She did have fun, but she still wants to make everyone miserable anyway.
- Win Her a Prize: Kevin attempts to win a stuffed animal for Hiromi as a surprise, but the game is heavily rigged against his favor; to the point he's out of money and pays any further chances in possessions. In the end, he accidentally wins a stuffed animal at a different game.
