Derek Brockway gets walking for Children in Need. On a nine-mile hike between Wrexham and Hope Mountain, he meets local people and explores the landscape. He also learns about some of the projects that are supported by Children in Need all over Wales. There’s a challenge, too: Derek wants Pudsey to show off some top dance moves at a celebratory party on top of the mountain at the end of the walk, but Pudsey’s repertoire is limited to waving and doing ‘thumbs up’. Dance phenomenon the Matsena Brothers are called in to help, but can they teach Pudsey the moves in time?
