"It's biting me! It's biting me!" Last night, I'm A Celebrity crossed a line.

On Thursday night's episode of I'm A Celebrity... Get Me Out Of Here!, Abbie Chatfield, Robert "Dipper" DiPierdomenico, and Adam Densten faced a confronting double elimination challenge.

During the challenge, the trio were required to stick their hands into a mystery box and guess how many creatures were inside.

While the mystery box was filled with mice and eels in previous challenges, Abbie, Dipper and Adam were faced with more than a dozen non-venomous snakes.

The challenge went smoothly for Dipper and Adam. But moments after Abbie put her hand in the box, panic set in.

"It's biting me! It's biting me! It's biting me!" she screamed.

As she broke down in tears, host Dr Chris Brown and a handler untangled the snake from Abbie's hand.

While Abbie bravely continued on with the challenge and made it into the grand finale, viewers have criticised the reality show for going "too far".

"That's bullsh*t, what an awful thing to do to people," one viewer wrote.

"That snake biting Abbie was f**king TRAUMATIC," another said.

"This sh*t is unnecessary," another added.

This is pretty fucked. The snakes would be the most agitated now that they've had TWO sets of hands poking around before Abbie. It's not exactly fair, is it? #ImACelebrityAU

Ok no offence but this is the second snake attack on #ImACelebrityAu & I know they aren’t venomous but it must be so traumatic for the celebs.

Poor Abbie that snake latched on. Do they not get fed a couple days before they're put in there for celebs to touch. #ImACelebrityAU #ImACelebAU

In recent weeks, the show has been criticised by viewers on multiple occasions for crossing the line.

In a previous challenge titled the 'Ice Ice Baby Trial', Grant Denyer, Jack Vidgen, Pettifleur Berenger and Travis Varcoe were tasked with entering a tank filled with ice cold water in order to pump a lever at the bottom of the tank.

For nine long minutes, the celebrities struggled with the freezing temperatures.

After coming out of the water, the celebrities could barely speak as they were wrapped in towels and space blankets by medics in an effort to prevent hypothermia.

"There's just a lot of pain," Vidgen told hosts Julia Morris and Dr Chris Brown at the time. "I can't move my hands."

Afterwards, the celebrities were moved to a nearby medical tent to warm up.

"I'm just really scared," Vidgen told the medic.

"Physically, it was getting to the point where I was going to pass out."

Speaking to The Huffington Post, television presenter Grant Denyer shared that the challenge affected him for days afterwards.

"It actually hurt a lot to the point where medics were called for all four of us in the challenge. They were deeply concerned for our wellbeing because we’re at the point where our organs were getting close to shutting down," he said.

"I paid for it for days after. We started doing this random challenge that comes up and I just kept falling over and passing out onto my bed with not enough strength as a result of [the ice water] challenge. I got whisked off to the medic for a second time."

On social media, some viewers described the challenge as "dangerous" and "concerning".

Not sure how that one snuck past the OH&S team. They all look seriously unwell after the ice bath challenge 🥶#ImACelebrityAU

I understand the challenges are meant to be... well... challenging. But I don’t think this was okay. It was dangerous and concerning. Did they go too far? #ImACelebrityAU

I reckon that could well have been the most challenging challenge. Ice burns on their faces. Hypothermia treatment. Sore joints for days. Serious dehydration. Not sure how I feel after watching that 😱😭#ImACelebrityAU

Being submerged in ice water is probably used as a form of torture somewhere in the world and the show's twitter account is having a laugh about it. #ImACelebrityAU

‘Cold water can kill you in less than a minute. It’s actually so dangerous it has killed people within seconds.’ From https://t.co/sAzMOLQjZi Please dont do this ever again. #ImACelebrityAU

They are celebrities not super humans. That ice challenge has gone a step too far. That’s not entertainment but torture. Hope that challenge doesn’t come back #ImACelebrityAU

The reality show was also criticised when contestant Toni Pearen was bitten by a snake multiple times on her face in a previous challenge.

Afterwards, Pearen was seen bleeding from the snake bites as she told the hosts: "You have to get me home to my kids."

In a statement provided to news.com.au, Pearen said that she knew she was safe during the challenge.

"At no time was I prepared to say the words 'I’m A Celebrity… Get Me Out Of Here.' I knew I was safe. I was attended to by a medic immediately. I knew the snakes were not venomous. I was definitely in shock but I was not in pain and I was proud of my courage and determination," she said.

However, viewers criticised the show for not pausing the challenge immediately after Pearen was bitten by the snake.

Toni was bit 3/4 times by a snake, and no one helped her. I’m sorry, but that is VERY wrong. That’s one step too far. #ImACelebrityAU

— Monique (@moniquemaywoods) January 5, 2021

The fact that this show just lets Toni get bitten on the face by a snake FIVE TIMES is a joke #ImACelebrityAU

— Hannah (@Hannah_LMN) January 5, 2021

Wow. Watching a snake bite off Toni’s face and now seeing Jack, Trav, Grant & Pettifleur go into hypothermia. Who’s the sadist behind the camera? #ImACelebrityAU

Since Big Brother first hit Australian screens in 2001, reality TV has become a staple in Australian homes on a nightly basis. 

From fiery and even violent arguments on Married At First Sight to the gruelling challenges on SAS Australia, it's a format known for its shock value – and I'm A Celebrity... Get Me Out Of Here! is no different.

Over the years, we've seen celebrities partake in horrifying eating challenges, jump out of helicopters, and even be electrocuted.

But when it reaches the point that the contestants fear their organs are shutting down and contestants are being bitten by snakes for our own entertainment, a line has undoubtedly been crossed.

As one viewer put it: "Entertainment shouldn't be at the cost of someone else's extreme pain and distress."

The live grand finale of I'm A Celebrity... Get Me Out Of Here! airs on Sunday night at 7.30pm on Channel 10.
