Devils' Museum in Kaunas, Lithuania, is included in the list of the most unique museums in the world. Three floors have horned creatures from around the world coming in different shapes, sizes, colors and made from different materials. The devils are mischievously smiling, peeking out of the dark corner, showing the evil menace grin or a scree giggle. Some of them can be distinguished from ordinary humans only if you see horns or a tail protruding from the shaggy hair.
