TIL Deathclaws are always sticking their tongues out

I got my first pet Deathclaw and just followed it around for 10 minutes looking at it. This is how I find out when it stands up with its snout in the air it’s sticking its tongue out to smell. Does the same thing when it’s idle. I’d only ever seen this animation from a looooong distance so I thought it was such a cool little detail to discover after years of playing.
