Season 5 begins with five teams (made up of an expert pumpkin carver, cake decorator, and sugar artist) creating Halloween-themed displays that capture a terrifying infestation.

Four teams remain for the challenge of creating a mutated and terrifying hybrid horror.

Grave robbery is depicted in Halloween displays, created by the three remaining teams. Actress Bex Taylor-Klaus helps judge the competition.

Season 5 ends with the final two teams creating terrifying displays with an undead dinner party theme. Cassandra Peterson (aka Elvira) joins the judging panel to help determine the winner of the $50,000 grand prize.
