Children who are looking for something really scary to wear for Halloween might choose to dress up as bats. These are, after all, among the most frightening and mysterious creatures that live on earth. They look ugly, with their beady eyes (they cannot see well, hence the saying “blind as a bat”), large and unshapely mouths, sharp teeth and long, pointed ears that resemble horns. Many of their habits, such as sucking blood, are repulsive. When children wear bat costumes, however, they can look at least as adorable as they do scary.
