motion activated skeleton

Most are triggered by sound (claps, shouts, or nearby noise). Some models use motion sensors or a combination of sound and motion. Activation typically turns on lights and plays built-in sounds when the trigger is detected.

Many arrive ready to use with little or no assembly required. Multiple listings explicitly state the prop is ready out of the box.

Some decorations offer poseable parts such as adjustable arms (often wrapped in foam), movable joints in hands and feet, and repositionable limbs so you can set different poses.

Common power sources include batteries (examples shown: 3 AA, 3 AAA, or 4 AA) and plug-in electric power. Some items list “No Battery Used.” Several listings note batteries are required but not included, while at least one listing specifies batteries are included.

Most have built-in audio that plays when the prop activates. Documented effects include ghostly laughter, howling, chain noises, and other creepy sound effects tied to the item’s activation.

Common materials include fabrics and polyester (including some listings of 100% recycled polyester), PE and other textile materials, various plastics (such as ABS), and some metal components for structural parts.

Common display options include hanging the prop by a rope or hanger, placing it on a tabletop or floor, or using groundbreaker-style figures that appear to crawl out of the ground.
