"Diaz Family Vacation" is the ninth episode of the first season of Star vs. the Forces of Evil.

It premiered on April 20, 2015 alongside "Brittney's Party".[2]


After inviting the Diazes on a trip to Mewni as a last minute anniversary present, Star and Marco must save them from a many-headed serpent.[3]


Star talks to her parents on the mirror phone about her father's upcoming throne-sitting lectures. Her mother notices the dimensional scissors she got from Princess Pony Head, but Star manages to play them off as Earth scissors. After she finishes talking with her parents, Marco comes in and tells Star it's his parents' anniversary. Star feels bad because she didn't get them anything and thinks they're cool, much to Marco's disturbance.

Marco gives his parents fanny packs, which he apparently gifts them with every year. While Angie praises Marco for his thoughtful gift, a guilty Star blurts out that she got them a trip to her home world, Mewni. Star takes everyone to Mewni and shows them the small villages, staying away from her castle so no one recognizes her. However, Star sees her father, so she drags the Diazes into the Forest of Certain Death. Rafael and Angie narrowly miss many dangers, including man-eating plants and monsters. Star spots her father tracking something and nervously tells Marco that she will take them home, but as soon as she turns back, Marco's parents are gone.

Star and Marco find a Hydra, the Diazes' clothes, and see movement in the hydra's stomach, coming to the conclusion that it ate Marco's parents. Star and Marco fight it off and defeat it by tangling its heads in knots. Just then, Star's father jumps in and slices the hydra's stomach open; the villagers recently devoured by the hydra are freed, but the Diazes are nowhere to be found. Star, Marco, and King Butterfly soon discover Rafael and Angie enjoying a hot spring.

Soon after, Star and her father confront each other. King Butterfly scolds Star for not staying on Earth as she was told, but Star points out that he's supposed to be giving a lecture. As it turns out, King Butterfly has been secretly fighting monsters to vent his frustrations, and Star realizes that she inherited her monster-fighting skills from him. They agree not to mention any of this to Star's mother and reconcile with a hug. Marco tells Star it's cool she got to see a different side of her father. Rafael suddenly walks by, still naked, and Marco shields Star's eyes, wishing that he hadn't seen that side of his father.
