xx,yy = Tile coordinatez where the Megaphone may be found.

Note: It does not matter which Megaphone you acquire and use first! The objectz will be called for in the listed order.
In this Custom Level, it is possible (intentionally designed that way, so the solver can "go wrong, go wrong") to use the objectz called for in other than in the intended solving sequence. If you find that you have failed to pick up and use a Megaphone, you will have to go back to a previous SAVE (hopefully not all the way back to the beginning) and keep the keeper of the GruntzMachine (Resourcez) on his toez!
