Gusta 
the quirky goat
I might be stoopid, and I do not want to take a tag away from someone.
Thought the gryph was called Gus, the whole “Gusty” thing was a play on the og mlp having a pony with that name, and think the characters just mistakenely call him such in the fanfic.
You are free to correct me, even if it’s just this single image, think what happens when you repost between boorus and keep the tags without fixing them, kinda similar to r34’s yugioh archetypes and their translations having like 4 tags with slightly different spellings for the same character.
