Here's a picture preview of tonight's Big Brother 2014 as the housemates star in yet another bizarre task.
In this evening's show, the housemates became animals in a wildlife documentary.
At certain points throughout the day, a David Attenborough-esque commentator would announce things that the animal housemates were doing... and they duly had to replicate the commentary.
The commentary included Mark doing his mating call and Christopher becoming interested. They began sniffing each other in an unusual mating ritual.
Chris began grooming Ashleigh by licking her ears and playing with her hair while Winston performed a toilet dance in the Bedroom.
Later, Ashleigh and Chris retreated to the watering hole and started to splash each other. and Winston performed his sex dance.
Chris and Ashleigh marked their territories while Ash the human chameleon had to blend into the background.
For passing the task the housemates were rewarded with a jungle themed party where they enjoyed food and drink while in animal fancy dress.
Big Brother 2014 airs tonight at 10PM on Channel 5 tonight.
