Professor Baldi appears in his normal form: a tall, slender man with a green sweater, blue pants, and brown dress shoes. However, a out-of-place black box covers his face, seeming to replace his head, like it was photoshopped into reality. In this docile state he's normally in, he'll usually just stare at you and remain silent. When angered (which is easy), he transforms into a more terrifying entity. The black box gets removed, black eyes and a very big, void mouth replacing them. His arms elongate, shaping claws that almost touch the floor. He becomes animalistic in this state and very aggressive, often screeching when he sees someone.
