The remaining six contestants enjoyed a half-duck for dinner after Fleur East and James McVey won four stars in the later Bushtucker Trial.
As soon as they'd polished off their meal, a laminate arrived summoning Emily, Harry and John in to the depths of the jungle for an evening challenge.
"It's gonna be awful, I know it," said Emily.
"But what I've learnt is the more awful the challenge, the better the reward. I'm hoping we get to win something really, really good."
The threesome eventually arrived at a miniature house with flickering windows.
"That looks scary, I don't know why. That's freaking me out," said Emily.
The front of the house opened to reveal it concealed a tunnel, which the celebs began to crawl through.
At the other end, they arrived in the "doll house of horrors" - a bright pink room covered in dirt and grime, furnished with a bed and a toy box.
"Throughout the night, various dolls will cry out for attention," said Harry, reading their instuctions.
"Your job is to find out which doll is crying, settle her down and tuck her in to bed. If you find and settle 20 dolls, you'll win a luxury breakfast for the whole of the camp."
Being a jungle doll house, it wasn't just occupied by toys, with flies buzzing about, and cockroaches and spiders crawling all over the place.
Emily squealed as she noticed the creepy crawlies, but eventually got on the bed with Harry and John.
The dolls' screams were accompanied by names, and the trio were able to identify the correct toys by pressing them to find out their monikers.
With scores of dolls lying around, it was a tough task - and to make it even harder, the lights switched on and off sporadically.
"It was difficult to concentrate, there were bugs being dropped on us," said Harry.
"The art of it was you had to try and remember where they were," explained Emily.
Eventually they'd managed to tuck up all 20 dolls, and escaped the terrifying room with their reward intact.
"If I didn't have Harry in John there, I don't know what I'd have done," said Emily.
"I'm so excited for the luxury breakfast. I'm gonna get some jam and rub it on myself!"
The campmates' morning feast arrived just hours ago, before the sixth elimination of the series took place.
I'm A Celebrity 2018 continues nightly at 9.00pm on ITV, concluding with its grand final on Sunday.
