A local pet store had a chinchilla for a while when I was a kid in the 90s and the softness of its fur was just unbelievable, like it shouldn't be possible. I still think about it often and haven't felt anything like it since. The best comparison I can give is when you're tripping on shrooms and feel like you're experiencing completely new colours, tastes or sounds but it's more real. It was a defining sensory experience for me.
I read this scifi book where a dinosaur-like creature clutched a human to its chest because it was lonely after being separated from its young. Over time the pressure from the embrace slowly crushed and twisted his bones making them heal into grotesque shapes while he was still alive. I think titty bear might crush you into a heap of mangled living flesh thanks to the safety protocols and its need to hug. All while whispering how much it loves you
This is the sort of footage that comes up in the investigation of the latest holodeck tragedy where they investigate how 5 starfleet officers died a gruesome death and the ship has been taken over by a sapient stuffed animal.
