Scooby-Doo, Where Are You!

After coming back from the movies Scooby-Doo and Shaggy come across a pick up truck and a suit of armor in the driver's seat. According to an ancient superstition the armor comes to life during the night of a full moon.

While Scooby-Doo is surfing, he encounters a creature in a diving suit. An old sea salt tells the gang that it's the ghost of Captain Cutler who is responsible for the disappearance of many ships.

The gang gets shipwrecked on an island that happens to be an old lair for a pirate. They find a map, but there is a warning telling them to leave the island. The warning appears justified when a ghost called 'The Phantom' is after them.
