“Princess Celestia was walking down the halls of Canterlot. After a while being only about one hour after breakfast her stomach roiled at her. Feeling the rippling of her tummy as it grumbled. Celestia threw caution to the wind. Celestia trotted to her room but her tummy rippled again grrrrrruuuuuuuuuuuuuuuummmmmmmmmmmmBBBBBBBBLLLLLLLLEEEEEEEEEEE Oh my.. I should get that checked. Celestia felt warmer inside her belly. Celestias tummy expanded stretching loudly and grumbling as it ripples. Celestia is dead in her tracks feeling her plot grow bigger as her tummy over cast all the growths.”
 
Maybe it’s just gas?
