Joanna and Kirsten light the way and show how to make beautiful lanterns. There's a circus-themed super skill as the Let's Go gang take on juggling, Abe gets snap-happy with a photographic cool move called snapshots and there are more fun-tastic animated facts about the human body. Let's Go-ers Isobel and Alex have a forest adventure and discover insects, teacakes toasted on the fire and how to build a cosy den. In the Supersize Showdown, Abe and Kirsten go head to head - with the help of their teams - to see who's quickest to crack the mighty marble maze.
