Secret Adventures: Spin (1993)

Sinopsis

Say "Hi", to Andrea Thomas (we call her "Drea") - seventh grader at Hampton Falls Junior High and the most imaginative babysitter since Mary Poppins. Drea has an unusual knack for winding up in the middle of things - like a wacky campaign for class president against Arlene Blake, "Miss Popularity". When black mustaches "mysteriously" appear on all of Arlene's posters (thanks to Drea's campaign manager and best friend, Kimberly), Mrs. Long, the school principal, steps in and expresses disappointment in Drea's actions.
