The Skeleton Guy is wearing a typical skeleton costume, which consists of a black suit with bone patterns over it. He wears a skull-shaped mask held on by strings, through which his eyes can be seen. His suit printing depicts the bones of a minifigure Skeleton on his arms, torso, and legs. His hands are white. He reuses the Leprechaun's clay pot in orange with a jack-o'-lantern design as a Halloween treat bucket, which has a black handle.
