Stingray

Following the destruction of a WASP submarine, Troy and Phones are sent to investigate. They are soon captured by an enemy submarine in the form of a gigantic fish, which takes them to the underwater city Titanica. There, they meet Titan for the first time.

The Stingray crew track the launch site of missiles fired on Marineville to a volcanic island. However, on investigating they become captured by the aliens responsible.

Commander Shore and Phones are taken prisoner by Idotee who uses an old Spanish galleon to attack ships. Shore demands that Troy launch Sting Missiles against the galleon but the Captain disobeys orders and boards the vessel. There he opens his air cyclinders in the control room but unknown to Idotee the cylinders are filled with laughing gas! The alien is laughing so hard he fails to realise that he's captured
