Pony Head

Princess Lilacia Pony Head, sometimes called Flying Princess Pony Head, or just simply Pony Head, (voiced by Jenny Slate) is a princess from the Cloud Kingdom of Mewni and one of Star Butterfly's best friends.

She previously attended St. Olga's Reform School for Wayward Princesses because of her rambunctious behavior. After headmistress Miss Heinous and her faculty were overthrown and driven out of the school in the episode "St. Olga's Reform School for Wayward Princesses", Pony Head helped turn the reform school into a party location.
