IT'S the chaotic highlight of every series of I'm A Celebrity... Get Me Out of Here!
Water cannons, movie grade wind machines, superhero outfits and giant bouncing balls all make the Cyclone trial an incredible TV event.
Tonight, Coleen Rooney, Danny Jones, Oti Mabuse and Richard Coles will take on the epic event.
If it goes to plan, the challenge can be a memorable bucket list moment, however, when it goes wrong celebs are left with bumps, bruises and, in some very unfortunate circumstances, painful injuries.
We've taken a look back through the trial's storied history for its most shocking moments - and some might surprise you:
Dec Donnelly's shoulder agony
After years of watching on the sidelines, hosts Ant and Dec finally tackled the fear-inducing Cyclone to raise money for Text Santa.

A decade ago, the Geordie Duo strapped on their knee and elbow pads and threw themselves into the challenge with gusto.
Ant said at the time: "We're doing the Celebrity Cyclone today. It's always fun to do, but it takes a while to do. It takes a long time to get everything set up and get all the paint bombs set up and all the sludge and the slime."
"Everybody who watches the show always wants to give it a go."
But it would be the first and last time for the pair, after Dec suffered a shoulder injury amid the madness.

He kept the incident private at the time, but reflecting on it years later he said he needed six months of physio to sort the problem out.
Matt Hancock's tiny pants
The former politician was public enemy number one when he jetted into the jungle not long after his much-criticised handling of the coronavirus pandemic as Health Secretary.
To his credit, the shameless ex-minister didn't shirk a challenge and that included the Cyclone.
Transforming into a caped crusader of sorts, Matt squeezed into a pair of tiny bronze hotpants that left little to the imagination.
Viewers got a good view of his tackle as he rotated in slow-motion on a revolving platform seconds before dashing into the watery obstacle course.
It amused and repulsed in equal measure, with many regretting their telly-viewing choices that evening.
Joel Dommett's head slam
The 2016 Cyclone was a particularly vintage year with many labelling it the hardest to date.
Sam Quek, Adam Thomas, Scarlett Moffatt and Joel Dommett were the fantastic foursome tasked with taking it on.
For Scarlett it was a dream come true, with her actively counting down the days until she could slip 'n' slide.
But for TV star and comedian Joel, it soon turned into a nightmare.
The Masked Singer host was mercilessly dumped onto his head as the water jets honed in on him.
Fortunately, he lived to tell the tale and secured precious stars for camp.
John Barrowman's special role
The Doctor Who star suffered a nasty ankle injury in camp just before the Cyclone trial in 2018.
John needed medical assistance and temporarily left camp to get fixed up.
He returned wearing an ankle brace and using a stick to help him over the uneven jungle terrain.
It meant he couldn't take part in the trial as planned. Instead, he was given a unique starring role.
As 'the keeper of the stars' John had to solve puzzles before campmates Fleur East, Emily Atack and Harry Redknapp could get their hands on the oversized stars to transport up the course.
Vernon Kay becomes Superman
The TV and radio star defied his towering frame's limitations as he marched relentlessly forward during the challenge.
Channelling his inner Terminator, Vernon would not be denied as he strode powerfully over the water, taking fans' breath away.
One viewer exclaimed: "Vernon is an absolute beast! All the other celebs sent flying after that first big water drop and he stayed put!"
To top it off, Vern did it all with a smile on his face while his co-stars were washed away.
The impressive feat was a precursor for the superhuman efforts Vern showed to complete an ultra marathon for Children In Need this year.
He rain 115 miles in four days raising more than five million pounds in the process.
Stacey Solomon gets drenched
The Queen of the Jungle didn't have it easy on her way to receiving the crown.
Stacey was pulverised by gale force winds as she bravely crawled up the slippery slope.
Such was their strength that a star was blown right out of her tight grip. She then hunkered down on her spot to protect what she had and clung on for dear life as the challenge raged on around her.
The telly favourite was the epitome of washed out as wave upon wave of water washed over her.
She looked full of relief as the final klaxon sounded, and it was just in the nick of time too as it didn't look like she had much fight left.
Nigel's novel technique
Controversial campmate Nigel Farage adopted a new approach to the Cyclone when he took it on in 2023.
After taking a while to gather all the starts at the start - with Ant and Dec commenting on his slow speed - he then took the technique on travelling up the waterslide on his knees.

"That's a new one!" remarked Ant of the politician's unusual tactic.
It worked though, with Nigel making it to the first point with just over a minute gone off the clock.
