TV host Martin Roberts was forced to face his "worst fears" as he lay in a tree hollow filled with water and snakes on I'm A Celebrity... Get Me Out Of Here!
The camp newcomer confessed he was terrified of confined spaces after the public chose him to take on the Hell Hollow Bushtucker Trial, but insisted he would try it as he did not want to let the other contestants down.
The first part of the task saw Martin rooting around for stars - each representing a meal for the camp - in tree hollows guarded by jungle critters.
But things took a terrifying turn when he came to the second part of the task, and had to lie in a hollow that was slowly filling up with water.
The property expert gamely tried to make light of his predicament, joking: "There's many a London flat that's smaller than this. Don't like the view. And it's got a bit of damp."
But he looked less jolly when the snakes started slithering into the space, wriggling over his face and neck.
Afterwards, he was told that the trial had featured 52 snakes in total - the most ever used in a Bushtucker Trial.
"That was pretty hard core," he gasped, as presenters Ant and Dec told him that he won eight out of a possible 12 stars.
Back in the camp, Martin was elated that he had got through the challenge.
He said: "I am delighted if I'm honest, because I've survived.
"I've conquered my worst fears, it was total mind over matter, focus focus focus."
But his joy turned out to be short-lived as he was later in tears over a row about water.
The trouble started when camp president Scarlett Moffatt asked Martin to help get more water for the camp and he ignored her, causing BBC Radio 5 Live presenter Danny Baker to see red.
"Martin, she's the president mate, whatever she says to do, you do it," Danny snapped.
The radio star accused Martin of treating Scarlett like "a silly kid" when he should be following her orders.
When most of the camp got into their hammocks for bed, Martin grew teary over Danny's stern words.
"Everyone thinks I'm treating you badly," he said to Gogglebox star Scarlett.
She replied: "Danny was sticking up for me, I've been made president and I'm very flattered and my job is to make sure everyone else is doing their jobs.
"Everyone else 100% gets stuck in but I've asked you over 20 times really politely and you just haven't. Then as soon as one of the guys asks you, you do it."
Martin apologised and vowed to turn over a new leaf.
I'm A Celebrity... Get Me Out Of Here! continues on ITV on Monday at 9pm.
