[Because Sora's in Ponyville when he sees this message, having paused in his exploring for a break, you get to see a small, dark charcoal gray/black pegasus pony with a spiky brown mane and tail and wearing a silver crown necklace. Judging by the image, he might have one of his Spirits holding the communicator for him at the moment.]

Hi. It looks like you've gotten a lot of answers already, but if you think of anything else, don't be afraid to ask. Everyone's generally pretty helpful.

Oh! I'm Sora. Nice to meet you.

[It hasn't occurred to him that maybe he ought to point out that he's not naturally a pony.]
