I looked up tons of pictures on google images of these two and the closest I could find was Discord holding Screwball with a screw between her hooves. I used that image for reference anyways and “painted” (used MS Paint) it so that her hooves were up in the air instead.  
Took me two and a half days to finish because trying to get the right colors for Discord on MS Paint was a b… er.. witch. And believe it or not, Screwball was the hardest to draw because of all of the curls in her tail, mane, and those eyes of hers. >.<
 
Anyways, here’s the picture I used for reference:
