Nighttime has fallen in Equestria. You were on your casual stroll through Ponyville until you heard a booming voice from nowhere-

"Make way for the princess of the night!!"

You could recognize that voice in an instant- It was Princess Luna, and she was coming this way. You stop in place as she approaches, only for you to feel surprised surrounding what had happened to her- Luna's belly had grown to an exponential size, mere inches away from touching the ground, her flanks were almost equally as large, and her cheeks had become quite chubby. She quickly sees you upon making her entrance.

"Oh, another subject out late, huh?" She says as she approaches you, belly and flanks jiggling.
