NEW Halloween 2019 Indoor/Outdoor Window Decorations – Scary Tapping Window Peeper

https://www.whatonearthcatalog.com/CY9702.html

Scare the bejeezus out of everyone that passes by your window, without even lifting a finger. A motion sensor triggers into tapping on the glass (or choose an auto-tap setting), with a creepy gaze completing the effect. Great for Halloween, and a must-have for prank-inclined folks. Plastic with suction cup mounting; 12″H.
