The riders rode on by them and he heard one call their name
If you want to save your souls from hell a-riding on our range
Then cowboys, change your ways today, or with us you will ride
Trying to catch the devil's herd, across the endless skies.
So, expanding the lore and concept of phobia species I thought about this, Pure and impure Phobias.
One being the direct representation of said phobia and the other is more free in other stuff
There can't be 2 Tropophobias but there can be several impure ones.
Fun fact:
My Phobia species actually started as a series of character skins for PonyTown, I made a lot of them over there and turn them into a more fleshed out concept and design.
