Agatha and her husband Bradford Sadler let Jerry and Terri visit them. Late one night, Agatha asks the kids to go to the nearby beach and look for her beach towel, but Jerry and Terri instead go to the caves. After the kids had their adventure, they went home only for Harrison Sadler's dog to bark at Agatha and Bradford. Agatha got mad at the dog for revealing their secret, as dogs can sense the dead. She asked Brad what they're going to do about the kids.
Brad and Agatha both have white hair, eyes that seem faded and tired. Brad is missing the top part of two of his fingers, which he claims is due to a wolf trap.
