He can not explain or share with anyone what he sees or why he sees it. However, this poor soul has watch the trolls throw tacks on the roadway and laugh as tires exploded over bridges. He has observed the elves spray painting on the sides of buildings. He has even seen a unicorn lick the top scoop of an ice cream cone and cause it to fall to the ground, leaving a mother to deal with a crying child.
