The Last Castaways

On holiday in Saltbottle, Grandfather and Roo discover the Unsinkable, the boat which took them to the North Pole, lying in a dilapidated state and up for sale. The short-sighted auctioneer accidentally sells the boat to Roo. Now they have to find the money and the Captain suggests a fishing trip to the Great Cod Banks in the Forgotten Sea.

In vacanta in Saltbottle, bunicul si Roo descopera barca ,,Nescufundata", care i-a dus la Polul Nord, intr-o stare darapanata si scoasa la vanzare. Licitatorul miop ii vinde accidental barca lui Roo.
