That’s the vest joke I’ve heard in a while.

I think it’s a plushie of a claymore mine:

This perspective kind of reminds me of Pyro from TF2. I’m imagining an AI mine, but they couldn’t disable the ethics guardrails, so they got around them by altering it’s perception. That mine is just looking for tired and lonely friends to snuggle to sleep so they can finally get some rest.
