Draco Dei
As I said on >>73663 Fluttershy’s image in this series, I fanon that Discord prank-cursed the coffee to cause cat-like transformation and/or behavior.
Since I see no signs of transformation here, I shall assume she about to get “the rips”, which might make the prank not nearly so harmless if one scales up the probability of a cat doing that to “supersonic capable Pegasus”… better hope she ends up zig-zagging outside sooner that than later, and then ends up maneuvering around obstacles rather than pin-ball-pouncing off of them…
