Asterix and the picts

When Asterix and Obelix rescue a mysterious Pict named MacAroon, they must journey to Caledonia, now Scotland, to return him to his lady love, Camomilla, the adopted daughter of the old king. However, the treacherous chieftain, MacCabeus, plans to marry her and claim the throne - with the help of the Romans! What with caber-tossing, bagpipes, malted water and an enormous otter in the loch, can the Gauls reunite MacAroon and Camomilla and enjoy some Roman-bashing along the way?
