Eddy Stone and the Epic Holiday Mash-Up

When Eddy finds a pirate in his gran's bath, his miserable summer holiday becomes a treasure hunt! Setting sail in a ship-shaped shed, crewed by an old lady and a grumpy penguin, what could possibly stop their quest for booty? (Apart from the world's most evil shopkeeper, a man-eating beast, and the maddest, baddest villain in all the seven seas.)
