I used three of my OCs, Fire Sparks, Carrot Root, and me as Film Reel, as seaponies. I put their Cutie Marks on the edge of their bodies instead of on their fins since I had no room for them there. And I was going to include Ocean Blue here, but she doesn’t need to be a seapony since she can be underwater without being one.
