Taking over Crystal Cove
|Chronological and political information|
The Song Of Mystery (Only appearance)
Mary Ann wanted to run Crystal Cove her way with no adults so she dressed up as Que Horrifico to scare the adults out of town. When she played the music, the children donned their monster disguises and scared away the parents.
When it came to the monsters cornering Mystery Incorporated, the television was turned on to a cartoon, distracting the children. When Que Horrifico tried to run, it was caught by surprise by the police car carrying Sheriff Bronson Stone and Mayor Fred Jones, Sr. and fell into one of the nets. Mystery Incorporated unmasked Que Horrifico revealing Mary Ann who explained her plot to drive away the parents and take over Crystal Cove. One of the children stated that her plan wouldn't have worked anyway. Sheriff Stone then grabbed Mary Ann with handcuffs and took her away while ranting to her about costing the town a fortune with merchandise such as Que Horrifico t-shirts, Que Horrifico Pan Flutes, Que Horrifico Dance CDs, and Que Horrifico... when Mary Ann replied, "Ok ok! I see your point." (The Song Of Mystery)

She is proud of her high IQ of 195 and believes herself well-qualified to take over the town.
