Last week we told you that for Fright Fest 2019, Six Flags Great Adventure is bringing back the 30-Hour Coffin Challenge for a 2nd year.

Last year's 30-Hour Coffin Challenge went totally viral and took the whole country by storm as thousands of brave souls applied to cram themselves into a coffin for nearly a day and a half.

This year, Great Adventure is making the challenge even more, well, challenging, while also bringing in a celebrity guest host.

First of all, the 2019 coffin challenge definitely won't be for the claustrophobic among us, as the park describes this year's tombs as each having a, "...fully-covered coffin lid with just a small mesh hole for that ultra-claustrophobic feeling".

In addition, participants will only get one 13 minute reprieve every 3 hours for bathroom and phone breaks, and they're upping the fear factor with, "...games that include live bugs, [and] pungent food items".

And perhaps the scariest part of the whole thing - they're going to keep the coffin-dwellers awake by playing "Baby Shark" on loop.

That's not a joke, either, so be prepared to have that stuck in your head!

The celebrity guest emcee will be Butch Patrick, who played Eddie Munster in the iconic TV show "The Munsters".

The heartiest soul will take home a prize package that includes $600, two Six Flags Gold Passes and two Fright Fest Haunted Maze Passes.
