Atop a web cover mound, a Spider patiently waits for his prey. His Infrared sensor activates with nearby movement flinging him towards the target. A wind up mechanism tethers the thick fuzzy sider to the mound dragging him back up for another round. 4 AA batteries allow him to be placed just about anywhere while the option for a power cord lets him run continuously for hours. An included step-here pad triggers him with one wrong step and lets your victim be particularly close.
