“Starswirl was a bit odd to create. He uses a different set of map sprites from everyone else so he just faces down, moves his staff, and blinks. Unfortunately, his eyes are a bit lower than they are in the original game, so the it read the wrong data from blinking. I ended up having to unravel how the game assembles his sprite and change how it stores some data to get it to work. As a result, the sprite sheet in the zip is formatted a bit strangely, giving him double eyes in the last frame.
 
His design when you summon him is based off how he appeared in the Sirens Fiendship is Magic comic.”
