Join Dave Lamb and Rattus Rattus as three more Horrible Historians travel down the time sewer to win year spheres. They take on quirky quizzes and gory games including Pirate Treasure and Gong Farming! But don't let them have all the fun - you can play along too and collect year spheres of your own. Just download the Gory Games App from the CBBC website. If you're of a nervous disposition, a bit squeamish or easily shocked, then this show is not for you. Show less
