On one Halloween, eccentric little 9 year-old Shelley Marie hesitated on which Halloween costume to choose between: a princess one and a villain one. Sensing her hesitation, a crew of Disney villains decided to give her a tour of the wonders of villainy to convince her to follow their dark path. And after stepping into the Magic Mirror, Shelley Marie met Dr. Facilier, Ursula, Maleficent and the rest of the gang. In the end, she was home, and her mom decided to go trick-or-treating with her.
