Plot[]
It is Halloween in Wizville, and everybody seems to be in the spirit, except for Penny Proud. When Penny is forced to don a costume to serve Proud Snacks to trick-or-treaters, and then is sent off to a Halloween party she cannot get into, she casually takes a bite of her father's snacks and develops superpowers. This happens just in time, since she has to thwart a major crime spree by the Gross Sisters and protect her family from the wrath of a miserable ghost.
