Today, housemates' bravery will be tested as they go head-to-head against a wild and savage gorilla for this week's shopping task. Housemates will be competing against world famous gorilla impersonator, Peter Elliot in a bid to receive a luxury shopping budget.

There will be a 'trained handler' and a 'wrangler' (both actors) present to ensure the housemates are safe at all times.

Big Brother will present each housemate with a gorilla cuddly toy which they have to cuddle to transfer 'their scent'. The 'gorilla' will then sniff out which housemate he wants to take part in the first challenge and after that, housemates will decide who will take part in the subsequent challenges. All successfully completed challenges earn the housemates 30 seconds towards the final task.

Challenge 1: The chosen housemate must enter the cage and pass a beach ball backwards and forwards with the gorilla. To succeed in this challenge, the housemate must get three passes between them and the gorilla and will earn 30 seconds towards the final task.

Challenge 2: Two housemates must enter the cage armed with a camera and some gorilla feed. Their challenge is to get a photo of one of them with the gorilla. If they get a good photo, they will earn 30 seconds towards the final task.

Challenge 3: A housemate must attempt to make the gorilla dance using their own dance moves and a portable CD player. If they manage to make the gorilla dance, they will earn 30 seconds towards the final task.

Challenge 4: One of the housemates must enter the cage dressed as a gorilla and they are told that they must bond with the animal. The gorilla will then get too close for comfort and start picking nits off of the housemate. Big Brother will indicate when the housemate can leave the cage.

FINAL TASK – Bananageddon: In the garden there are 500 bananas, each worth £1.00. All housemates will have the amount of time that they won to collect as many bananas as possible – however, during this time, the gorilla will be roaming free.
