With Snatcher and his men safely guarded by the trotting badgers, the Nautical Laundry has resumed order once more. But new problems have arisen. The antidote they so desperately need is on Black Cabbage Island. And the island is fiercely guarded by a strange and terrible-looking monster. If, and when Arthur and his friends can get past it, what else will the island hold? Meanwhile, back in Ratbridge, the cheese lust is surging out of control and the gaol is overflowing with cheese-hunting fiends. The sanity of the town, and the lives of the cheeses, all depend on the antidote ...This is part three of the wonderfully-weird Worse Things Happen at Sea!, illustrated throughout by the author in fabulous detail.
