Grim was added to the yard in 2006. As was common for props on their debut year, he was positioned close to the front door. He has a 24 inch pneumatic cylinder triggered by a motion sensor. In an unplanned benefit, there’s a slight delay between when the sensor goes off an when he jumps, possibly because the air is building up pressure through the system. All I know is he’s wonderfully timed to lull people into a false sense of security.
The first year he had plastic landscaping fabric for a cloak. That gets updated later…
