M3 likes to be a snuggle robot.
Every once in a while the older two pretend to be robots. M3 got into it too, but her robot always hugs. For a while, several months ago, she'd be a robot if we asked or if the others were pretending.
Now she just comes up with it out of the blue. I was shoveling a few days ago and suddenly a robot came out of the garage to snuggle me.
During the video she is saying "robot, robot" for her first attack and "snuggle, snuggle" for her second attack.
