Mainly the idea would just to be a a specific TF to give the player character horns or make their current ones grow. The only TFs I've seen with horns are ones that drastically change the character as a whole. This one would just be like a pill or an injection. The name would probably be something like "AntlerUp" or some other cheesy pun. If I can figure out the coding, I'd try and write this myself but for now I just felt like putting this here.
