I remember back in the Spring seeing the previews of the Japanese version of this short and everyone was saying it was definitive proof that Sylveon was a flying type (something to do with the way the flowers were blowing when it first appeared, proving that it had been flying around, the egg frame around it in that one scene, the clouds on the title screen, and I kid you not, people saying that the setting was "sky friendly.") There were some arguments that Sylveon must be a "cosmic" type, but turns out that the cosmic looking scene was created by other pokemon. Kinda funny watching this with that debate in mind.
