The island with the ghosts has a grey teleport brick which you use to enter the tomb, get Dracula's blood and the keys to release Dizzy.
When you have all the ingredients to make the stink stop spell you discover that the blood is a studio prop and throw it away - this triggers the last button to drop down,
Once all the buttons have dropped you can enter the combination to get the key to the gates of Pornia ....that is if you've discovered all the parts of the combination that have been hidden around the game - or prepared to spend three days checking every possible combination.
