This viking duo will give Horrid Henry a run for his money!

What if your parents WANTED you to behave badly?

Set in the snowy fjords of a Viking kingdom, the terrible twins, Hack and Whack, are proud to be the best worst vikings. Nothing stops the marauding pair as they steal boats, loot a birthday party, track a troll and sail off to raid Bad Island with their friends Twisty Pants and Dirty Ulf.

Well, almost nothing . . .

With whip-smart dialogue, and accompanied by Dennis the Menace style anarchic cartoon imagery, this series is as sharp, funny and compelling as you would expect from the reigning Queen of Comedy.
