Woolfrik and Perigold are two down-on-their-luck cats in need of some extra cash, so they've decided to become professional monster slayers - except they don't know the first thing about it! So when a huge beast starts rampaging through the town, they are put to the ultimate test.

But the monster is just the beginning of their worries, because someone even more troublesome is pulling its strings. So even though they've never been in a battle - or even gone on a real quest before - it's up to these cats to save the day and prove they've got what it takes to be heroes.
