Then they get to flex their imagination as they create a gigantic Halloween feast for a special guest of honor. From 3-D frog brains to pumpkin pepperoni pizza, judges Marc Evan and Terri Hardin have their work cut out for them to decide who goes home and who remains to fight for the title of Outrageous Pumpkins Champion.
