Once upon a time, in the spooky town of Mysteryville, Scooby Doo and his gang, along with their trusty Mystery Machine, arrived at the ancient Egyptian Museum. They heard rumors about a mummy that had come alive and was causing all sorts of trouble. With their detective skills, they were determined to solve this spine-tingling mystery!

As they entered the museum, they saw ancient artifacts and hieroglyphics decorating the walls. A voice echoed through the halls, saying, 'Beware, anyone who disturbs the resting place of the pharaoh shall face the curse of the mummy!' Scooby and his friends shivered with fear, but their curiosity pushed them forward.

They wandered deeper into the museum, when suddenly, they heard a loud crashing sound. They followed the noise and discovered a secret passage hidden behind a massive statue. With a gulp, they entered the dark and eerie tunnel.

The further they went, the more they sensed they were not alone. Suddenly, a shadowy figure appeared, wrapped in bandages like a mummy. It let out a bone-chilling moan! It was the mummy! Scooby and his friends gathered their courage and decided to unravel the truth.

Through their investigation, they discovered that the mummy was actually Mr. Jenkins, the museum curator. He had been using the mummy legend to scare people away, so he could search for hidden treasure in peace. Scooby and his gang confronted Mr. Jenkins and saved the day!

The museum thanked Scooby and his friends for solving the mystery. With the mummy now unmasked, the town of Mysteryville was safe again. Scooby and the gang celebrated with a big feast, where Scooby indulged in his favorite treat—Scooby Snacks!
