MYSTICAL APPEARANCES

attack it, it turns into a deadly opponent. You may only cause damage to it 
by throwing a dark red crystal at it, or dropping a granade (blue crystal).
Unicorn: A harmless animal by nature, but unfriendly when attacked. Calm it 
by feeding it black crystals.
Phoenix: An animal that cannot be defeated. A friendly conveyance to a 
random room, when selected
