Dont get fooled by his appearents, one of things he can do the best is hinding, most of the time his live depends on it.
He is unable to walk in bride daylight, because his skin would simply get burned asoon the smallest ray touches him.
The only time he can go outside is at night, he really likes long strolls through the woods or to swim in large lakes.
The fastest way of finding him, would be to look out for that faint turquoise glow coming from his body, but asoon you would have a trail, he will be gone : 3
