Para Mask Koopa
From the Super Mario Wiki
A Para Mask Koopa is a type of Mask Koopa (A Koopa with a Mario mask) with wings. It is only found in Super Mario World after the player finishes all the special levels on Special World. These creatures acts the same way as Koopa Paratroopas, the only difference is the Mario Mask that they wear. When jumped on, they will lose their wings; a second jump will make the Koopa inside the mask drop the mask. Mario will then be able to defeat the Para Mask Koopa.
