So currently, their seems to be a bit of confusion as to how ghouls should be categorized. Should they be only Ghoul or both Ghoul and Pony type. Even more confusing is how to deal with Canterlot Ghouls compared to normal Ghouls. Personally, I think we should have a separate, single categories. Under this system, Ditzy Doo would be Category:Ghoul (Pegasus), Applesnack would be Category:Ghoul (earth pony), and Silver Spoon (Project Horizons) would be Category:Ghoul (earth pony).
I'd like to hear the community's thoughts on this.
EDIT: Community dicission is to include both tags for ghouls. Any creature who is made totally different by a mutation (maintains none of their previous abilities), only use the final state of that character.
