Mud was a 1994 CBBC television show, starring Russell Brand, Brooke Kinsella, Russell Tovey in their early appearances and a teddy bear called Steve.
The series revolved around a group of children from a London tower block who were sent on holiday to an outdoor activities centre called Felfront Heights, along with their social worker. The first series revolved around their adventures at the centre. In the second series, the children found that the centre had been closed down so the social worker took them to a local village. They became involved with a witch finder, who had spent hundreds of years tracking down a local witch. The children travelled into the past, thanks to a time-travelling ambulance, in order to prevent Mrs Dears becoming a witch in the first place. When they returned to the present, the children realised that they had inadvertently changed the course of time, and the present was significantly different from how they had left it—most shockingly, they realised they had stopped America from being discovered by Europeans, and consequently, and paradoxically, there was no such thing as television.
