This is the flying Kamek sprite used in a few levels of Yoshi's Island, which flies in a loop from the background to the foreground.
It starts by moving left in the background at whatever height you place it at in Lunar Magic. Once it goes offscreen, it'll fly right in the foreground starting at Mario's height. When it goes offscreen there, it'll go back to the BG.
Graphics for the original Kamek sprite are included, as well.
Sorry for not noticing the missing graphics in the last update, I extracted the zip in the same folder where I had the graphics from the other submission, so I thought they were already included... silly me.
