This is how Ghoul Rescue goes in
[Shaggy, Scooby-Doo, Scrappy-Doo, Matches, and Umarak the Hunter arrive at Revolta's castle]
Shaggy: Wow! Your tail did the job.
Scrappy-Doo: Gee, this place is humongous.
Umarak the Hunter: Ha. I'm not afraid of anything. [goes into Revolta's castle]
[Shaggy, Scooby, and Scrappy follow him inside]
Revolta: What are you going to do? Obliterate me?
Umarak the Hunter: You leave my friends alone!
[Umarak takes off his Hunter Mask and puts on the Mask of Control and becomes Umarak the Destroyer]
Umarak the Destroyer: Prepare to be destroyed!
