The five remaining I'm A Celebrity ... Get Me Out Of Here! contestants won all five stars in the Celebrity Cyclone Bushtucker Trial.
Presenters Ant and Dec told bookies' favourite Vicky Pattison the challenge was "new and improved for 2015".
All five celebrities - including fellow participants Ferne McCann, Kieron Dyer, Jorgie Porter and George Shelley - had to get the five yellow stars on to the markers.
"You can stop the trial at any point by saying I'm a celebrity, get me out of here, but we won't hear you because it's too loud so just carry on!" the Geordie duo joked.
Hollyoaks actress Porter went first. Next up was Geordie Shore's Pattison, who had balls, water and air blasted at her at full force.
A ball hit The Only Way Is Essex's McCann in the face and she lost all the stars as a result. The TV personality had to go back to the beginning.
Former footballer Dyer also lost his grip on the stars.
Ant and Dec did not escape unscathed - they were splashed by the water and air.
Union J's Shelley completed the trial, with the quintet bagging five meals for their endeavours.
"Nobody said we were going to get wet as well!" cried Ant and Dec.
When the celebrities arrived back at camp, they were told five choc ices had been hidden and they had to find them before they melted.
All five contestants found the treats and agreed it had been "the best day".
The camp mates discussed their best and worst jungle moments.
Essex's McCann said: "Honestly, my high point was the snake trial. I can't put into words how terrified I was. I hate trials, but bringing back 10 stars - you can't buy that feeling. It was incredible".
Dyer revealed his low moments came with the departures of boxer Chris Eubank and Lady Colin Campbell, dubbed Lady C on the ITV show.
"My worst part was when Chris and Lady C left, I was so grumpy. That was tough for me as I'd formed such a great relationship with them and didn't have that bond with other camp mates.
"At the time when those two left, I thought that was the end for me. But it helped me develop stronger relationships," he said.
Soap star Porter talked about Disaster Chef, her memorable Bushtucker Trial.
"My lowest moments were being in Snake Rock when we had no food. Disaster Chef! That was the most strongest I was - I ate three cockroaches live, that was horrific."
"I'd like to thank you all for being part of the best experience I've ever had," said Pattison.
For the last night in the jungle, the five celebrities were treated to a slap-up meal.
Music was played in the camp so everyone danced and sang.
