The Guardian mummy has a "Start-minigame" option in order to start the minigame quickly. If a player successfully loots a Pharaoh's sceptre from a Grand Gold Chest, Annoyed guardian mummy can be briefly seen in some of the rooms saying Grr, someone has found the pharaoh's sceptre! Right! That's it. I'm clearing all the urns and refilling them now. The player who found the sceptre will never see him as he immediately removes them from the Pyramid.
