Third Uncle, You're a Little Embarrassing

Henry thought to himself that the Haunted House was quite capable and had put in a lot of effort in making the props. He had already walked in front of the wedding dress and was only an arm's length away.

Henry sized up the wedding dress and was about to circle around to see if there were any clues when he suddenly saw the wedding dress move. It bowed slightly to him.

Henry was stunned. He looked at the wedding dress that had yet to get up and thought to himself, "How did they do this?" He leaned closer to take a look and realized that there were no clothes hangers around the wedding dress. There was nothing hanging on its back. There were no steel cables, pressure lines, or anything else.
