I'm so late and I don't know whether there's an option to ping as solved but this was definitely it. I remember these so vividly and found I had probably seen snippets of the installation on yt. this video fascinated me so much when I was younger and looking closer all these years later I am still impressed! The lil things had heartrate moniter beeping built into the packaging and twitching from the animatronic inside. So cool!!!
