Finnian is an anxious little bean who is terrified of everything. His eyes are always covered due to a traumatic past experience he doesn't like to talk about. He cannot see anything in the way others do, but he is able to sense his surroundings. However, these senses are not always accurate, which causes him to bump into others and obstacles occasionally. The fear of bumping into someone much larger, angrier, and not-so-much forgiving causes him to worry constantly when venturing outside his home.

He is very, very fluffy. He has so much wool, which he tends to be a bit obsessed with keeping clean, that he is able to store smallish things inside. 90% of the time he is kept warm by it, but on really harsh, wintry days, he may need an extra layer or two.
