Amanda Roberts — a ghoulish make-up artist, horror-punk musician and self-proclaimed Halloween enthusiast — was always a safe bet to take home the top prize in this year’s 30-Hour Coffin Challenge at Six Flags Great Adventure.

Over the weekend, the 31-year-old from Hopatcong survived 30 hours in a fully covered coffin, with limited bathroom and cell phone breaks. She also earned the most points while competing in the contest’s creepy mini-games, eating pork brains, fishing for items in a cockroach-filled jar, bobbing for candy in green baby food and more.

As the grand prize winner, Roberts won $600, two Gold Season Passes for next year, tickets to the Haunted Maze, and a small replica of her coffin. Roberts works at a Halloween store and practices body suspension (hanging herself from hooks through temporary body perforations).

Keri Platt, of Forked River, won second place. The 47-year-old mom nearly died at childbirth, and last year she donated a kidney to save her mother’s life.

Six contestants participated in this year’s challenge after 6,000 people applied to compete.

All runner-ups won park passes and Fright Fest memorabilia.
