Frank isn't any ordinary monster. He is a kind, gentle creature, but is often hated because of his grotesque appearance. He lives in the closet of children, like many other monsters. Whenever he comes out to say hi to the child housing him, however, the child only screams. Frank then retreats in fear, because he is afraid of parents, and what they might do to him. He only wants to be friendly, but no one ever likes him.
