It is revealed in the NES ending that Nick and Tom are human princes. These ghosts can't be killed or stunned, so the player's only hope is to avoid them while eliminating the rest of the enemies to move on to the next screen as soon as possible. After a short time the evil pumpkin will spawn ghosts that can travel freely through the level and seek the player character. It is invincible but can be stunned and sent to appear somewhere else in the level with snowballs or snow shots. If the player takes too much time to complete a level an evil pumpkin head will come and try to kill the player character. The effects of the red, blue, and yellow potion wear off after the player loses a life.
