A mash up of another scene taken from the Sonic the Hedgehog Saturday AM pilot episode “Heads or Tails” featuring a pink colored Sally Acorn with an image of Pinkie Pie from My Little Pony: Friendship is Magic thrown in (two pink animals in a crossover pic, eh?) and the caption has Pinkie Pie singing a line (with Sally’s name incorporated) from a Season 7 MLP:FIM song called “Flawless”.
 
This is part of the SOCIAL MEDIA push to get Sally Acorn to be a part of the 2018 IDW Sonic the Hedgehog comic book relaunch (Of course, IDW also publishes the My Little Pony comic books! - Could this pave the way for IDW after the Sonic comic gets launched in early 2018 or so that later that year we might see a Sonic/My Little Pony crossover miniseries?)
