Forni, the Satyr, joined Quickdraw on his journey to help educate humans about mythological creatures. Forni is not faun, not horse, nor bull.
For Forni, being a satyr is half human & half goat.
Half human & half deer is a Faun.
Half human & half horse is a Centaur.
Half human & half bull is a Minotaur.
And if Forni had a fish tail instead of goat legs, he would be a Merman, not a Mermaid.
