Panic erupts among the I'm A Celebrity stars tonight as they are trapped in glass 'coffin' filling up with water.
Each of the celebs have to find the keys to unlock themselves - while surrounded by slithering snakes, crocs and an array of critters in the water.
Nadine Coyle, Ian Wright, Jacqueline Jossa and Roman Kemp have to undertake tonight's trial, Sinister Circus.
In a preview for this evening, the stars frantically try to search for keys to unlock the padlock.
Queue screaming from Nadine, who says she "hates it".
"What was the next thing we have to do after the padlock?" she asks Ant and Dec as she clings to the ladder.
Dec tells her that she needs to get down into the water and raid the cupboard below.
Nadine ducks her head down but admits she can't do it.
"Snakes!" she exclaims as Jacqueline heads below.
Meanwhile Roman and Ian struggle to get past the first stage and unlock the padlock.
Nadine tries to head underwater again but fails and shouts in frustration.
Will the celebs be able to succeed or will they return empty handed?
*I'm A Celebrity airs tonight at 9pm on ITV
