The seventh Scooby-Doo direct-to-video film where the gang encounters the Loch Ness Monster. Scooby-Doo and the Loch Ness Monster was produced by Warner Bros. Animation and Hanna-Barbera credited as the copyright holder despite the former fully absorbing the latter by this time.Grey DeLisle returns voicing Daphne and will remain as such from here through the rest of the franchise, not to mention itís the first time Mindy Cohn voices Velma and for the rest of the franchise as well.Also, as from here until Scooby-Doo! and the Samurai Sword, this movie was produced in the same animation as What's New, Scooby-Doo?, no longer having the retro feel of the previous two films.Mystery Inc. travels to Loch Ness in Scotland to see the famous Blake Castle, where Daphne's cousin Shannon lives, and where the Highland Games are being held. But there's a problem. Apparently, there was a recent attack made by none other by Nessie herself. Shannon also claims to have seen the creature before, and claims that it is real, siding with local enthusiast Del Chillman and Professor Pembrooke, a scientist who staked her whole career on proving the monster's existence. However, Sir Ian Locksley, the head judge of the games, thinks just the opposite, causing a mutual hatred between him and Pembrooke.
The next night, Shaggy and Scooby are chased by the monster, ruining the game field in the process. The gang searches the area for clues, and sure enough, they discover that the monster tracks lead into town instead of toward the loch. Whether they like it or not, they've got a mystery on their hands.
This film contains examples of the following tropes:
- Bookcase Passage: There's one in Blake Castle.
- Conspicuous CGI: The Loch Ness Monster itself.
- Cool Boat: Sir Ian Locksley's got one.
- Earworm: "You take the high road, and I'll take the rocky road! Like, rocky road ice cream, that is!"
- Everything's Louder with Bagpipes
- Haggis Is Horrible: Not even Scooby and Shaggy will give haggis a try.
- Lots of Luggage: Daphne. Lampshaded at the end.Shaggy: Maybe next year there can be an event called "the long-distance Daphne Blake suitcase carry"!
- Meaningful Name: Del Chillman.
- Monumental Damage: The monster knocks a tower clean off Blake Castle at one point, with Shaggy and Scooby inside it.
- The Mutiny: Sir Ian's crew turn out to have ambitions of their own and try to catch the monster for themselves, interfering with the gang's trap.
- Mythology Gag:
- The gang dealing with the Loch Ness Monster had been done before in the 1972 New Scooby Doo Movies episode "The Loch Ness Mess" with the Harlem Globetrotters.
- Daphne's cousin Shannon describes the Blake family as being "danger-prone" and having a history of falling into all sorts of traps. "Danger-prone Daphne" is classic in-series nickname due to how often she was captured or trapped.

- The Prankster: Colin and Angus.
- Red Eyes, Take Warning: The monster.
- Road Sign Reversal
- Scooby-Doo Hoax
- Shout-Out: The Loch Ness Monster's design in this film is almost identical to the Paleosaurus. Both films were from Warner Brothers.
- Stock Ness Monster: It's the real deal. Well, actually, one is a submarine and one is Del's van, but there's potentially a real one too.
- Sub Story: The gang travels into Loch Ness in a sub to explore underwater caves.
- Walk on Water: Shaggy and Scooby manage to run on water using oars.
