Chute!
Imagine going on a guided tour of BBC Television Centre, where you're shown round the studios, the Blue Peter garden and even the place where the rubbish goes. But then you accidentally fall down a chute and end up in one of the BBC's tips, where you meet Ross Lee, who's also trapped down there.
But it's not that bad! The place is full of videotapes with hilarious clips from old TV series, outtakes and other silly stuff! There are even pilots of shows that never made it on air!
There are guest occasionally visiting Ross, like CBBC's Raven, Bill Oddie, or a pair of Saturday morning numpties! But look out for the Monster though!
