Ed Petrie and friends go on a bizarre quest to find the most unusual, strange and amazing places to visit in the UK.

In this episode, CBBC megastars assemble for the ultimate face-off at the World Custard Pie Championships in Maidstone. The team discover Viking graffiti inside a 5,000-year-old Orkney tomb, explore Belfast's hidden gems with Game Show Man and bemused locals, take a boat trip through King Arthur's Labyrinth in Powys with American travel vloggers Mandy and Clifford, and sing their way around the UK's craziest events, while Max and Harvey play a very silly geographical quiz.

Ed is joined on this amazing and offbeat road trip by Naomi Wilkinson, Annabelle Davis, Lauren Layfield, Max and Harvey, The Gaming Beaver, Eman Kellam, Joe Tasker and Lee Hinchcliffe - bet you didn't know this stuff was in the UK, but it turns up All Over the Place! Show less
