Competitive Hollie Arnold and Shane Richie were losers in the latest trial as they managed to win two stars out of a possible six.
The pair took part in Wicked Waterways based in two separate tunnels.
Hollie and Shane had to use a single bucket and work as a team to transfer water through the tunnels and into the collection pipes.
Once they had enough water in the collection pipes, the stars would float up and they could collect them.
There were six in total each worth two meals for camp.
Shane, 56, went into the top tunnel to collect the water, Hollie the lower tunnel to collect the bucket and pour it into the pipes.
The pair kept talking to each other as they worked out how to get the bucket to each other but it was not a smooth process and there were issues with it getting stuck and them losing water.
To make matters worse they were joined by bearded dragons, naked rats and cockroaches.
They ended up with just two stars meaning four meals for camp shared around the 12 contestants.
Paralympic champion Hollie, 26, said afterwards: “It was tough.”
Shane added: “We made it tougher. We set a precedent, this is the first one when we’ve kind of dropped the ball.”
When they returned to camp the others found it hard to hide their disappointment.
Victoria Derbyshire said: “We’ve eaten like Kings and Queens the past few days and this is a real come down.”
