Well, they don't. They've never seen one. But when they spot a poster of what they think is a dragon, they just know that they've been called upon to save the whole of Sheepdom once more ... this time on the Isle of Wight! Their fourth quest is the fiercest u and funniest u yet, and sees our fearless adventurers on the trail of a dinosaur egg, pursuing a huge-handbag-swinging thief and becoming the star attraction in a spectacularly chaotic carnival procession.
