Where is the blue skull on the Kmart haunted house game

Begin in the room with the Bat door, which is the locked exit.

1. Move through the door into the main room, which has the staircase to the upstairs rooms.
2. Go left into the first room, and avoid the ghost to pick up the Pumpkin key.
3. Continue right and get the Blue Skull from the second room (the candy there cannot raise your energy unless you were hit by the ghost)
