The Holl is a creature you do not want find in this game. It pops out of a trunk in a tower, while you're looking for the prince/princess during a tower rescue in the Forest. Once you make your choice of towers, the end result is unavoidable. Sorry. Go get healed, and don't guess that tower location next time, because until you guess correctly, the Holl will always be in the same two towers out of the five.
