...well those steps lead to the new treat room:
The treat room is purple and yellow and contains a hot tub (which is truly hot), two beanbags and a cupboard filled with goodies (which Big Brother can refill from the back as he sees fit).
But again, not all is what it seems. Firstly, the door is inches bigger than a catflap, and only those who can fit through get in. Secondly, only a maximum of three housemates at a time are allowed inside, and it will only be open at times suited to Big Brother.
And that's it!
