The tenth feature in the Scooby-Doo Direct-to-Video Film Series, Scooby-Doo! Pirates Ahoy! was produced by Warner Bros. Animation, featuring pirate ghosts in an attempt to cash in on the then-current pirate trend started by Disney's Pirates of the Caribbean: Dead Man's Chest.
For Fred's birthday, his parents take him on a mystery cruise, but accidentally end up solving all of the mysteries staged by the crew in order to keep the passengers entertained. However, can they solve the mystery of that mysterious castaway over there?
Scooby-Doo! Pirates Ahoy! provides examples of the following Tropes:
- Amazingly Embarrassing Parent: Freds mom and dad embarrass him in front of his friends by treating him as if he's still a little kid.
- Bedlah Babe: Velma dresses up as a harem girl for a costume party.
- The Bermuda Triangle: The film takes place at the Bermuda Triangle.
- Blinding Camera Flash: A Running Gag in the film involves whenever Fred's parents snap a photo with their camera, the flash temporarily blinds the photo subject for a few seconds.
- Brainwashed and Crazy: All the pirates are actually hypnotized people except Skunkbeard's first mate, Mr Mysterio, who actually did all the hypnotizing.
- Captain Colorbeard: The main villain of the film is a pirate ghost named Captain Skunkbeard.
- Continuity Nod: During a montage of the Mystery Inc. gang solving all the mysteries staged by the cruise crew, we see them unmasking the Ghost Clown and a werewolf that were both seen in Scooby-Doo, Where Are You!.
- Crying Wolf: In a sense. The Scooby Gang start the plot on a mystery cruise, where the captain and the organizer set up every "Scooby-Doo" Hoax in the book to stump them but get seen through every time. Unfortunately, they end up so desensitized that when a real mystery falls into their laps they don't initially believe it.
- Dramatic Unmask: Played with when it comes to Scooby Doo's usual hoax unmask. When they unmask Skunkbeard, they assume Wellington is one of their basic bad guys - pretending to be a supernatural pirate in order to get some kind of treasure. Then it turns out he really thinks he's the reincarnation of a famous pirate. The gang is initially nonplussed, and the real unmask turns out to be his first mate.
- Even the Dog Is Ashamed: Scooby voices his disapproval at Shaggy's reluctance in confronting the ghost pirates, since they captured Fred's parents.
- Ghost Pirates: The main antagonists are ghostly pirates.
- Ghost Ship: Captain Skunkbeard has his own ghostly ship.
- Hypno Fool: Mysterio was hypnotizing everybody into acting as the pirates, and convinced Wellington, likely with some hypnotism, that he was the reincarnation of a pirate many years ago, and could use the meteor to travel back in time.
- Latex Perfection: Not just the pirate ghosts, where the crooks and everyone that was hypnotized were wearing pretty good full-head rubber skull masks made up to look ghostly, but for some of the "mysteries" that are part of the cruise early on, such as Captain Crothers wearing a latex skull mask at one point while sticking his rubbery head through a hole in a dining table and platter to scare passengers.
- Parent Service: Daphne dresses as a Cat Girl and Velma dresses as a Harem Girl/ Bedlah Babe in the costume ball, most likely to provide fanservice for older viewers.
- A Pirate 400 Years Too Late: The ghost pirate Wellington was convinced that he was the reincarnation of a famous pirate years in the past, and thought that he could use the meteor to travel back in time.
- "Scooby-Doo" Hoax: Mr. Mysterio hypnotized everyone so that he could steal the meteor, which is pure gold.
- Sherlock Scan: At one point, the Gang are asked to figure out where a guy's watch is after singlehandedly solving all of the mysteries on the ship, and manage to perfectly guess where the man's watch is just from guessing what likely happened.
- Shown Their Work: The TBF Avengers of Flight 19 and the USS Cyclops were accurately rendered.
- Theme Tune Cameo: When Shaggy and Scooby-Doo dress up as Daphne and Velma to try and get into the costume ball, an instrumental arrangement to the theme to The New Scooby-Doo Movies briefly plays. Also doubles as a clever Call-Back.
- Wholesome Crossdresser: Scooby-Doo and Shaggy try dressing like Velma and Daphne, respectively, to get into the costume party.
- Wink "Ding!": After rescuing Fred's parents with remote-controlled kit planes, Velma and Scooby wink to each other, accompanied by xylophone "clink" sounds.
- Why Don't You Just Shoot Him?: As pointed out by JelloApocalypse of So This is Basically... fame, why didn't Mysterio just hypnotize the astrocartographer into helping him, like he might have done with Wellington?
