I can’t help but question if this is a different artist that did the other art under the same name.  
Artist description  
This whole thing was an odd last minute thought, but it was so funny… I hadda go with it. My original idea was Discord in a costume that looks like Fluttershy and it terrified her friends… while she was off running an errand, blissfully unaware of the horror going on
 
I still like that idea… but I had a lot of ideas for this TG—this one won out. It WAS going to me Slender Man just standing there, all ominous as usual… but I thought it would make it funnier if he was doing something “friendly” and was still scaring Discord.
 
Fluttershy hoofpalm… awesome
