Star Vs. The Forces of Evil

Star Vs. The Forces of Evil is a 2015 animated series created by Daron Nefcy for Disney XD. It stars the magical extra dimensional princess Star Butterfly as she takes refuge on Earth while she learns to control her magical wand, as the twin threats of Ludo, a diminutive monster who covets her wand, and St. Olga's Reform School For Wayward Princesses, where Star will be sent if she messes up too badly on Earth, loom.

Saint Olga's Reform School for Wayward Princesses
In a special thirty minute episode, Star and her Earth friend Marco (disguised as a princess) infiltrate Saint Olga's to retrieve Star's friend, Princess Flying Pony Head, for her birthday... only to find that she's been sent to the "Solitary Conforment Chamber", brainwashed. Marco is later captured and subjected to the same treatment, being rescued by Star and the cured Princess Pony Head just as he begins to succumb. Flustered by Star and Marco's violent intervention in her school, Headmisstress Ms. Heinous begins to feel her own programming slip, and subjects herself to her own brainwashing program to regain her composure.

Deep Dive
In this episode, Star gets hypnotized by Janna to stop her sleep-portaling when it becomes a danger.

It is also revealed in this episode that Janna hypnotized Marco to go to sleep every time he hears "chicken butt" and it is used multiple times in this episode.
