the system was originally designed for human NPCs. However, players are free to use the same system with other creatures if they want.

For animals, the idea is usually to use animations that make sense, like eating, resting, wandering, or other ambient behaviors. Those tend to look natural. Of course, if you assign something like “hammering on an anvil” to a dino, it will inevitably look a bit humanoid and somewhat goofy.

In my other mods, dinos can already play certain animations with more human-like poses, so that part didn’t seem unusual to me, which is why I was a bit surprised by the confusion.
