2. Episode 2

Quirky quizzes and gory games. The contestants have to see how many flies they can catch, and they are pretty big.

3. Episode 3

4. Episode 4

Rattus has borrowed Dave's watch without his permission. Also, there is a coin to release from Barmy Brunel's throat, some keys to find in some pretty slimy pirate barrels and Henry VIII is demanding pies to be fed to him.

5. Episode 5

Dave is pretty fed up with Rattus' new game Plopscotch. He's definitely going to need a change of shirt. The Horrible Historians try to work out how to build a pyramid and make two identical portraits of Queen Elizabeth. They watch out for Emperor Vitellius, and a cauldron of truly horrible Garum Sauce.

6. Episode 6

The seagull is back at the Battle of Trafalgar - it's amazing that it manages to dodge the cannon balls being fired straight at it. William the Conqueror's tomb is being looted again and you so know what's going to happen! Yes, his stomach will explode. It's so wrong, it's right!

7. Episode 7

There is nothing quite like firing a severed head from a catapult to get you in the mood for some fun! The Roman Savage Siege is in full swing in this episode, along with one of Rattus' other favourites: Tudor Gong Farming - all that poop!

8. Episode 8

9. Episode 9

Contestants raid a pirate's treasure, find out if the God of Cupboards was real in Roman times, work out the sequence of cogs to stop barmy Brunel choking on a coin, and finally get covered in poo.

10. Episode 10

11. Episode 11

William the Conqueror is back in his tomb waiting for another set of looters to grab as much colour-coded treasure as they can - did we mention that his guts would explode? There are WW1 words to decipher and enough garum sauce to fill several Roman cauldrons. Dave and Rattus are around to make sure there is fair play.
