Sabrina the Teenage Witch #20 (1998)

Head witch Enchantra transfers Sabrina to her "girl's school for witches" in the other realm. Since it's a private school, however, she's forced to wear a uniform and adhere to the school's strict rules -- which are boring even for a witch! Back on Earth, her aunts and Cousin Ambrose are aware of her plight, and plot an elaborate rescue. Can the silly sorcerers bust our favorite teenage witch free? "A Monstrous Halloween": When Sabrina refuses to go to her family get-together to attend a mortal Halloween party, she's transformed into a creature more ridiculous than any costume she could possibly wear!
