The Big Brother 2017 housemates have been transformed into babies for their latest task.
In possibly the final task before Friday's final, the housemates are going to right back to their starts in life
Isabelle and Tom were the first housemates to take part in the task, dressed as giant babies in the task room.
Big Brother told the pair: "This is Big Brother, Tom and Isabelle, welcome to the first stage of life, early childhood.
"Shortly, Big Brother is going to ask you a series of questions.
"In order to answer each question, you must search through the coloured blocks and spell out a word correctly."
Questions included 'What kind of tree produces acorns?' which the pair concluded was a pine tree.
Tom and Isabelle correctly stated that India is part of Asia and that an eggplant is the vegetable better known as an aubergine in Britain.
As the pair answered the majority of their questions correctly, they passed their part of the task.
The task will continue on Tuesday with some familiar faces.
Evicted Big Brother 2017 housemates will return to the house tomorrow, it's been revealed.
Channel 5 today teased the upcoming task that will see the former housemates make a surprise comeback.
What their role will be in the task has not yet been revealed but they'll appear in Wednesday night's highlights episode.
In addition, Big Brother has revealed that a further TWO housemates will be evicted via the backdoor before the final.
They will be booted out secretly sometime on Wednesday night before their exits are revealed in Thursday night's episode.
Big Brother 2017 continues nightly on Channel 5.
