The ninth installment in the Franchise/ScoobyDoo DirectToVideo series produced by [[Creator/WarnerBros Warner Bros Animation]], ''Scooby-Doo! in Where's My Mummy?'' was the only one to get a limited theatrical release in selected cities of the United States.

Velma has been in Egypt for six months helping out Prince Omar, who's working on restoring Art/TheSphinx, so the gang tries to surprise her by visiting. However, they run out water in the Mystery Machine's radiator. While looking for water, they meet an Egyptian nomad Amahl Ali Akbar, who shows them the way to the sphinx. When they arrive, they meet the former host of a show called "Fear Facers," Rock Rivers, who hopes he can come to Egypt and get some footage to revive his show. Eventually, Scooby picks up Velma's smell, and they find her, surprising her as they had originally intended.\\
Velma introduces her friends to Omar, then shows them an ancient necklace she found within the tomb of Cleopatra. However, treasure hunter (and grave robber) Dr. Amelia von Butch shows up with her crew to loot Cleopatra's grave. Using modern equipment, they open the tomb via explosion. Once the grave is opened, it unleashes a curse made by Cleopatra, stating that all who enter shall turn to stone. Nobody believes it, so von Butch decides to enter the tomb anyway, despite the fact that Omar had recently been separated from the others and turned to stone. Once in the tomb, a trap is set off, splitting up the gang.
!! This film provides examples of the following Tropes:

* AdventurerArchaeologist: Velma has beome one. Von Butch is [[GraveRobbing the evil version]].
* ArtisticLicenseHistory: The Battle of Actium is portrayed as Egypt being conquered by the Romans, which is simpler to get across than the Roman faction Cleopatra allied with fighting the one she didn't.
* BerserkButton: When Velma drops her glasses, they're picked up by [[spoiler: a mummy, who supposedly turns Velma to stone. Scooby Doo, being a dog, is loyal to all his friends, and]] that is something you '''don't do!'''
* BigDamnMovie: It's an awfully complex plot on the character's part.
* BigFriendlyDog: Scooby adores Velma, and it shows in the scene where after picking up her scent, he barrels into her much in the same way he usually does with Shaggy.
* ChekhovsGun: Scooby's ability to recognise scents leads to the reveal.
* CrouchingMoronHiddenBadass: Scooby and Shaggy jump from a falling platform to save their lives.
* ADayInTheLimelight: This is Velma's movie.
* {{Foreshadowing}}: When Von Butch arrives, Prince Omar notes, "Velma, we must act quickly." [[spoiler:This was a hint for both Prince Omar and Velma creating the plot.]] Also [[spoiler: the above mentioned BerserkButton... Well, Velma "can't see without her glasses", remember?]]
* HollywoodAtlas: The film portrays the pyramids of Giza as being many miles from civilization but they are actually on the outskirts of Cairo, of which Giza is a suburb.
* ItBelongsInAMuseum: Velma says this about Cleopatra's treasure.
* MonumentalDamage: At the end, Shaggy sets off a giant firework, which collides with the Sphinx's nose.
* {{Mummy}}
* MythologyGag: In the 1969 episode ''Scooby Doo and a Mummy, Too,'' the gang had faced a mummy whose m.o. was turning people to stone with a curse [[spoiler: [[FridgeBrilliance in fact this might have been where Velma got the idea for the]] [[ScoobyDooHoax hoax]]]]
** [[spoiler:Velma dresses up like Cleopatra. She did so previously in the 1969 episode ''Scooby Doo and a Mummy, Too,'' as she, Shaggy and Scooby were trying to elude the mummy of Anka.]]
* PragmaticAdaptation
* ScoobyDooHoax: [[spoiler:Velma was behind it all, dressing up as Cleopatra, and using Prince Omar and his workers to dress up as the mummies in order to scare away treasure hunters.]]
* SeductiveMummy: PlayedWith; Cleopatra first appears as a beautiful woman, before turning into a scary crone. [[spoiler: It is later revealed that she was actually Velma in disguise, and there are hints at a romance between her and Omar.]]
* SpannerInTheWorks: [[spoiler: It turns out the Scooby Doo Gang nearly became this for Velma's plot, which was to scare off the grave robbers, when they showed up]].
* WeWouldHaveToldYouBut: [[spoiler:Velma and Omar do not let the rest of the gang on their plan to scare off the treasure hunter Amelia von Butch with a Cleopatra hoax. As Velma put it, "it was too dangerous". ]]
