The Troll longs for a goat - but has to make do with fish for supper instead. Meanwhile, Hank Chief and his pirate crew are digging for treasure - but it seems they've sailed to the wrong island. Again. Watch the fun unfold as these two worlds collide in a richly inventive, gloriously comic tale from Julia Donaldson and David Roberts, the creators of the highly acclaimed Tyrannosaurus Drip.
