Dr. Mario’s cape texture is normally a 2:1 texture mirrored vertically. With this, you can put any square image on it. Comes with the very good skill cape texture to let your friends know that it’s actually very skillful to smack them with your cape’s giant hitbox, and not at all annoying or cheesy.
Note: the image will be reversed on the other side of the cape still, as his cape isn’t separately textured on the other side
