It's a terrible, horrible place, and no one who goes there ever comes out the same!

St. Olga's Reform School for Wayward Princesses is a prison-like reform school for princesses, formerly run by Miss Heinous.


On the outside, St. Olga's Reform School for Wayward Princesses resembles a grand Victorian-style castle, with a large stone building with pointed roofs surrounded by several stone towers. The school is surrounded on all sides by tall, indestructible walls made of haveltroth stone and lined with barbed wire. It is also maintained by Gemini and guarded by robot sentries.

Among the courses taught at the school include dressing appropriately, interacting with animals and nature, tea party etiquette, proper throne posture, and others. The school also prides itself on suppressing the individuality and free spirit of its students. Particularly stubborn and opinionated cases are sent to the Solitary Conform-ment Chamber, where they are strapped to a chair and forced to watch slideshows of proper princess behavior.

Other areas in the school include Miss Heinous' office, a tapestry chamber, the laundry room, and the library.

St. Olga's Reform School seems to be infamous within the princess community; both Star Butterfly and Pony Head fear the school greatly because they always scream whenever the school is heard or mentioned. According to Star in "Match Maker", a princess is never the same after attending the school.

As of "Sleep Spells", two named princesses are known to be in attendance at the school: Pony Head (for her behavior) and Princess Smooshy. According to Star, if her mom finds out that she failed to behave and be responsible with the wand, she will be sent there as well.

In the self-titled episode, Star and Marco sneak into the reform school in order to liberate Pony Head for her birthday. In doing so, Star finds the institution to be worse than she imagined, as the staff brainwash the princesses into being mindless, prim and proper ladies. After they free Pony Head, she and Marco incite a revolt among the princesses, damaging parts of the school and toppling the Tramorfidian Crystal Tower.

In "Goblin Dogs," Pony Head reveals that Miss Heinous has left St. O's, and that it has since become a "total party school".

In "Heinous", Miss Heinous reveals that, following the rebellion that Marco incited, the princesses at the school lost all respect for authority, started skipping classes just to party, and started fraternizing with princes from a neighboring reform school.

In "Princess Turdina", the school has become a party place with little to no order and it's become very messy and disoraganized. Princess Arms appears to be the school's new de facto leader.

In "Skooled!" is is revealed that the school was originally run by the robotic St. Olga, which was deposed at some point by Miss Heinous. She eventually returns to reaffirm her suspicions of her royal lineage, attacking several princesses and breaking Pony Head's horn as she lays waste to the school.
