He has a round, stout body with short limbs, similar to his brother. He's green and has a huge stitched mark across his forehead, with screws on each side of his head, resembling Frankenstein's monster. He has spiky, dark green hair on the top of his head. He wears a purple jacket, a green-striped shirt, grey pants, and black shoes.
He is usually seen alongside Icky, implying they may be twins. Boris helps set the table for supper and is said to have gotten the lead role for a school play, together with Icky. They also help Wilhamena notice and try to defeat the ghosts, Spanky and Crudde taking over Rad and K.O.'s bodies. He does not seem to speak at all.
