Ep 6. Set Sail for Adventure

After Stingray destroys an attacking submarine, another soon arrives to threaten Marineville. Foiling the assault, Troy, Phones and Marina pursue the sub into a deep undersea tunnel and come across the city of Solarstar. As the high water pressure threatens to crush Stingray's hull, it seems that nothing can stop the Solistans in their plan to destroy the West Coast of America.
