Scooby-Doo! Pirates Ahoy!.Fred is treating the Mystery Inc. gang to share in his birthday present: a mystery cruise, compliments of his parents Skip and Peggy. While preparing for the ship launch, Scooby and Shaggy have a creepy encounter with a sinister-looking cloaked man, whom the duo are sure is up to no good. The gang meet the hyper Cruise Director, Sunny St. Cloud, and the captain, Captain Crothers. The Captain says they are bound for the Bermuda Triangle, and St. Cloud promises some creepy intrigue. A montage of sloppy "mysteries" that are staged by St. Cloud and Captain Crothers follow, which the gang solves with ease. This peeves the other guests, who have no mysteries to solve now. Soon they rescue Rupert Garcia, a man lost at sea, who tells of an encounter with ghost pirates. The gang naturally assumes that this is a setup to another mystery. He is taken below deck as a man in a jetpack appears from the sky and lands on deck. He turns out to be Biff Wellington, an English billionaire who is known to be fun-loving yet eccentric. He plans to stay on the ship as well...
