Overview: It's the quarter-final and the five remaining woodworkers turn up the heat and go wild as they take on animal sculptures. They must chainsaw and carve their way through this colossal big build and unleash their inner beasts as they attempt to uncover an animal within the wood, in just two days. Judges Alex de Rijke and Helen Welch also set them a physically demanding skills challenge that takes them back to Viking times, but only one woodworker can win the immunity that will guarantee them a place in the semi-final.
