The Teacher is an elderly, slim woman who dresses similar to school teachers from the 1910s, with a gray skirt, a beige buttoned-up shirt, white socks, and black Mary Janes. The Teacher is a relatively large monster, with a height of about four times that of a child. She looks about 30, with baggy eyes, graying black hair, and a wrinkled mouth stuck in a permanent smug grin. Her most striking trait, however, is her neck- when she stretches it up to 10 meters to catch bad behaving children .
