Warp to Gloom & Doom Down in the Tomb - Part 2
When playing the game, go to 'The One Way Trip To the Crypt' level with the warp gate on it. Activate it and go to the warp gate North-West from the one you are on and press X. Even though you haven't even gone into this level, you can get Scooby snacks and beat the Green Ghost. To make sure that the cheat has worked, go down the path where the buttons are and go through the gate. You see the locked gate, but when you go near it, it opens.
