And all we can say is: O.M.G.
Watch the trial:
Scarlett Moffatt, Ola Jordan, Sam Quek and Jordan Banjo have to endure ten minutes entombed in the pitch black cavern while 120,000 critters are thrown in over them.
It's the most amount of creepy crawlies ever used in an I'm A Celebrity task. There are spiders, rats, crickets, cockroaches and more crawling over the stars as they lie on the ground and desperately wait for the ten-minute mark to pass.
So, so gross!
Team GB Olympian Sam tries to keep everyone's mind off the disgusting challenge by questioning what food they'd be eating at home. "Chicken kebab!" screams Scarlett.
Scarlett, Ola, Sam and Jordan were chosen for the challenge after all failing to complete the Saviour Challenge in time on their first day. Each of the ten celebrities had to take on a scary challenge on behalf of another camper: the twist was they had to complete it in a certain amount of time or the camper would face the bushtucker trial.
It actually worked out quite well for these four however: Scarlett and Jordan were on a team, and Sam and Ola, so at least they all failed for each other, rather than one of them passing for a teammate only to find out the teammate had failed for them.
The whole bushtucker trial is shown on Tuesday night's episode of I'm A Celebrity, airing 9pm on ITV.
