Hunger, insects and a complete lack of privacy all help create the perfect storm for a massive barney in the I'm A Celebrity... Get Me Out Of Here jungle.
Over the years there have been some major eruptions - from ground-shaking diva strops to campmate bust-ups and brutal betrayals.
This year, Covid-19 has put the kibosh on flights Down Under, meaning the brave and the bold will have to make do with Wales.
While they will be spared chowing down on kangaroo testicles and witchetty grubs in the stomach-churning trials, campmates will instead have to contend with the dark, damp Gwrych Castle in Abergele, North Wales - and its spooky inhabitants.
As the ITV show gets set to launch its 2020 series, Mirror Online takes a look back at the its most torrid and turbulent moments...
Iain Lee and Amir Khan eat the winnings
Strawberrygate gripped the nation in December 2017 when? Iain and Amir shamelessly demolished their Dingo Dollar prize ?without letting the other campmates get a look in.
Amir then let radio host Iain take the blame for eating the strawberries, revealing: "I was scared. Iain, when he came into camp, he didn't have the best reputation. Obviously the way he acted and he split the camp up."
He went on: "My teammates would never expected me to do that. I put my hand up.
"Iain provoked me to do it. I mean he pushed me to do it.
"I did feel guilty but I kind of fixed it a bit by saying 'you wouldn't have liked those strawberries and that cream was so hot'."
But Iain was left getting most of the flack from his campmates, who were angry and disappointed by his actions.
Viewers felt some of the remarks Iain got verged on bullying, but he later said the word was "a bit strong".
However, he did cancel a planned trip to Pakistan with Amir, saying he was "actually lying" about the events in the jungle.
"I was disappointed people had been saying things behind my back about having a game plan and not trying hard enough, but when you're in there you do go nuts, you can have days of doing nothing," Iain added.
Hugo Taylor's 'weird happenings'
Made In Chelsea's Hugo starred in the show in 2012 and exhibited some bizarre behaviour, which he later put down to "very weird and real" dark happenings.
He explained the? lack of food due to repeated failure in the trials, meant many of the campmates acted oddly on camera.
"We had some really weird things happening in the jungle that we unanimously have never spoken about and probably never will," he said.
"Things happened off camera because people had no food."?
Worried producers reportedly even flew in special vitamin supplements to help the campmates.
But Brian Conley was forced to quit the show after falling ill with malnutrition and exhaustion.
Brian later admitted he had stopped taking the anti-depressants he'd been on for 15 years, despite producers urging him to continue.
And by the time he left on day 10, he was in a bad way.
"They sedated me in hospital and gave me a tablet that would probably knock out a horse for two days. I woke up with a saline drip in my arm thinking, 'what on earth has happened here?'" he told ITV's Lorraine.
"ITV is a big huge company, they have got to do it right and if I've brought these tablets in, I've got to take them."
Gemma Collins' diva strop
The TOWIE star quit after just three days following a multitude of meltdowns on the 2014 series.
She screamed blue murder in the helicopter before it had even taken off for the camp.
“Can you stop a minute, please, I’m serious, just stop, I need to get out, seriously I’m going to be sick, I can’t do it, no way," she pleaded, demanding to instead be driven in.
Next up she threatened to quit because the walk from the car was too long, had an expletive-laden meltdown over a bug in her hair and threatened to kill herself if the campmates couldn't have a "treat".
She ultimately got thrown into the 'jungle jail' and forced to live off porridge. And that was the breaking point.
"People who murder get treated better than this. That’s the truth. Even a murderer gets fed three times a day," she barked before quitting.
However, she later explained that her fragile state was down to a "personal and very serious incident" that happened just hours before her flight to Australia.
Gemma had called police to her home alleging that she'd been assaulted by an ex.
She later dropped the charges, explaining that she "was too scared to see it through."
Helen Flanagan's meltdowns
Coronation Street ?star Helen held the dubious accolade of being the most unsuccessful Bushtucker Trial contestant ever.
Some challenges she failed, others she just walked away from despite her campmates being starving.
Not that she'd given the gruesome tasks much thought before she went in.
“I didn’t actually really take the trails into too much consideration because I didn’t think I would be doing so many trials,” she admitted.
“I thought I'd do one or two and I’ll give it my best and I'm strong-minded, I'm sure I’ll be fine. I suppose I didn’t realise the implications really, I just thought we’d kind of chill around the campfire in a bikini and make friends."
But she saved her biggest blow-up for after she left the jungle, breaking down during her eviction, cancelling three pre-arranged TV interviews and locking herself away in her hotel room.
The sobbing star visibly shook during her exit interview on the jungle bridge and was whisked away for a full medical as she clung to her mum Julia.
And she spent the whole of the following day barricaded in her room with her panicked parents.
At the last minute, she cancelled interviews with ITV shows Daybreak, Lorraine and This Morning, telling her? Twitter ?followers: “Thankyou so much for anyone that supported me in the jungle...
"Ive felt so emotional today and completely overwhelmed and mixed emotions.”
A show insider said: “Helen caused a nightmare by pulling out of her interviews.
"Producers were expecting to shoot three live links to the morning shows but were told Helen was too ‘emotional’ to leave her suite.”
Brian Harvey's bottom burps
Former East 17 star Brian quit the jungle in 2004 after a blazing row with Janet Street Porter over his penchant for breaking wind.
It all kicked off when he let one rip near where she was cooking dinner.
"Perhaps you can cook dinner tomorrow and I'll come round to your house and fart in your face," a furious Janet suggested.
"I need to f**king fart because all I've eaten is f**king beans!" Brian argued.
But it wasn't their first beef over boffing and Brian packed his bags in a strop and walked soon after.
Natalie Appleton screams for 'mummy'
Like Brian, All Saints star Natalie wasn't cut out for jungle life - especially after being nominated for five consecutive Bushtucker Trials.
She wept through each one, screamed "help me mummy - I'm going to be sick!" and even had to be given oxygen on one occasion in series four.
On day two she sobbed, "I don't think I can do this, this is not me, I don't think I've got the strength. I can't snap out of it. I'm not mentally prepared for this right now, I can't do it."
However, she had a nice diversion in the form of her blazing catfight with model and camp mate Sophie Anderton, who she branded a "prima donna".
Gillian McKeith's 'fake' faint
The poo detective had just been nominated for her seventh Bushtucker trial when she suddenly fainted on live TV, prompting her camp mates to speculate that she was faking it.
She was whisked away from camp by medics while Linford Christie completed her trial.
But comedian Dom Joly and actor Nigel Havers weren't buying it.
"I smell Baftas for that faint, I really do," said Dom, while Nigel remarked, "The faint was just brilliant. It's just the timing was so good."
She also smuggled in seasonings in the lining of her knickers and point-blank refused to do the Dreaded Digger trial, leaving her campmates starving.
