So this might be too late considering the possibility of pachyrhino coming out sometime soon in a dino pack (just speculation) but I was thinking of a way to make the pachyrhino more unique and interesting and perhaps each individual could have a randomized boss (the horn)? The way it could work is that the model for each dino is the same but the area where the boss is could have some kind code to randomly generate different bumps and grooves on the boss. Probably would be too technically hard to do but just an interesting idea. Alternatively you could have several premade bosses that randomly get picked when you create the dino in the lab.
