Leigh Nunan and I made a talking plush Turret from Portal. It can sense when you’re there, when you pick it up, and when you knock it over, and it responds appropriately.

Valve nailed it with Portal 2. GLaDOS, Atlas & Peabody, Cave Johnson, Wheatley and yes, the sing-song Turrets. This is a plush toy Turret with built in motion sensors that emotes our favorite lines when you pass in front of it, topple it or lift it off the ground. Please mass produce.
