Pirates of the cat sea. Kn. 7. The fire is thrown!

Koshd skewers are doomed: the cat Kholm Strait rises, and its islands go under water. There is nowhere to run - the strait is locked by the troops of the Sultanate of Guinen, and an uprising is brewing inside. And so, in such difficult times, a ship with golden sails enters into skewers ...
Captain Johnny Vorushki, his faithful friend Kukabar and the mysterious passenger of the ship head to the island of Oracle to pull out the lot of fate. But this is only the beginning of their exciting trip! The heroes have to commit many impudent actions, and in addition to build a submarine, find treasures and get acquainted with the amazing underwater people who keep the richest cultural heritage of the islands.
Can the heroes save Koshda skewers? Does their fate lead, or do they choose their own fate? And what role do sea cats play in all this?
