Help getting shoulder mounted dino

I’m making a perch for shoulder mounted dinos to be rested upon and I need to somehow get the dino that is currently on the players shoulder. If anyone can point me in the right direction, that would be awesome. Is the shoulder mounted dino treated the same by the game as a player on a mount? If so, is that the direction that I should be looking to figure this out?

Edit: I may have put this in the wrong section?
