* Scooby snacks: The delicious treats that Scooby-Doo loves.
* Gloom and doom: A spooky, dark, and scary atmosphere.
* Down the tomb: Suggests a creepy, underground location like a crypt or a mausoleum.
Here's how we can turn this into a Scooby-Doo mystery:
* The mystery: The gang (Scooby, Shaggy, Fred, Daphne, and Velma) might be investigating a spooky haunted tomb. Perhaps they've heard rumors of a ghost or a curse.
* The clue: They find a trail of Scooby snacks leading down into the tomb. This is unusual, as Scooby doesn't usually drop his snacks.
* The suspect: Maybe a spooky figure is using the snacks to lure Scooby and Shaggy into a trap.
* The solution: The gang will use their detective skills and Scooby's keen sense of smell to solve the mystery. They'll unmask the culprit and discover the truth behind the spooky goings-on.
