Wallter was tall (10 feet) and had grey skin. His torso was a darkish seashell color, and his legs were just dark grey. His head was round, and he had a little smile on it. He had round hands, too, along with longish grey arms. He wore a blue scarf, wrapped around his neck.

He jumped down from an arch that was made out of bricks, grey ones. He ran into the elevator, slightly ducking because of how tall he was. He stood at the front left side of the elevator, staying silent.
