Meet Sand Glider :3
 
Sand is a changeling that is still nervous about the past history of the changelings and how other ponies may think of them, since he knows not everyone will forgive them for the attack on the Royal Wedding. As such, he rarely transforms, and only turns into his changeling form when he is in private. He’s sad about this, as he wants to be his true self without worry or fear.
 
Besides that, he is a fairly outgoing and cheerful pony, who has a job working at the weather factory sorting out the clouds. He is also interested in sports and exercise as well.
 
He currently lives with his boyfriend Pond Splasher, who is the only pony who knows about him being a changeling.
