Halloween is celebrated at Palm Woods and all the guys don costumes, including Kendall, who dresses as a werewolf and doesn't reveal his identity to Jo.

Kendall and Jo try to keep their relationship quiet in an effort to appease Jo's publicist, who wants people to think Jo and her costar are an item.

The guys hold their annual prank-day contest and the girls at Palm Woods want to participate, so it soon becomes a battle of boys vs. girls.
