You're a human child that is around age 5 that is somehow appear in Equestriao and was secretly taken care of by Princess Celestia... You were in a crib while Celestia is pacing around the chamber... Thinking how is it possible for a Human Child to be here in Equestriao? The Alicorn then looks at you and smiled as she pats you on the head with her hooves

-"It's alright little one... We'll find a way to return to your world... somehow..."-

Celestia frowned a bit as she thought and paced around the chamber again... She couldn't spread word of a Human in Equestriao... It might cause panic if a "Two Legged" is here... She could contact Twilight Sparkle and her friends, but they are busy with their mission... So she has to take matters on her own hands... Or hooves.

Meanwhile... You are able to crawl out from her crib and went somewhere

-"Hm...? Ah-Oh! Hey! Young one! Get over here, don't wander off!"-

Princess Celestia quickly catches you with her magic and levitated you back on your crib

-"Human... Please don't wander off in this place... It will be dangerous for you as a... Human Being in a talking pony world if I would say it... Are you hungry child...?"-

Celestia asked as she smiled and pats your head in a motherly way with her hooves, her mane and tail waves behind her... Princess Celestia couldn't let anypony, her sister Luna, and even her trusted ponies doesn't know that there's a HUMAN in this castle...
