It's the Great Pumpkin, Juniper Lee - S2.E1

Every Halloween all monsters become humans for the night; but a monster called Mark has contracted an agent demon, Vikki Devyne, for make him human forever. Thanks to Vikki Devyne, all the now human monster children are unable to change back into monsters, and the parents turn to June to help. However, she has to make deals from getting a protein shake to wrestling a demon that goes by the name of "Jordan The Destroyer" managed by a Don King-hairdo styled wrestling promoter before midnight, or else they will not turn back into monsters and remain human permenantly. Will June do this in the nick of time?
