Halloween Witch One Piece is a surprise-type Prism Stone.
A dress composed of a black blouse with sleeves ending above the elbow. A black ribbon ties around each cuff to match the thin black string goes across the shoulders. A black ribbon is tied to the top and ties around the neck, while a white spider web is depicted on the torso. The skirt is purple light pleating and has images of black bats and a single cat. A big black bow rests at the center of the stomach with an orange center. Black pleated ruffles line the bottom with a long black bow attached to a thin line, one on each side of the skirt.
