As she slumbered gracefully in one of her favourite midnight fantasies making Princess Celestia a new dress for a grand occasion, Rarity was unaware that the bed she was sleeping in was slowly groaning as the wooden frame strained under her increasing weight. Her delicate form was expanding in all directions and it wasn't long before her hooves were already far beyond the bed's head rest and foot rest. Before she could be dubbed the new official dress maker for royalty, in her dream she heard the snapping of wood, the popping of joints and felt the jolt of the ground beneath her giving way for seemingly no reason. Her dream ended with a colossal crash as the bed could no longer hold her new growing form now four times her normal size. Clambering desperately to get the top cover of her bed off of her, she looks down to see the shock before her! Maybe that new experimental bedtime lotion that she used from Twilight has some kinks to iron out. XD

Another fun picture with my favourite pony experiencing a new phenomenon. =p

Enjoy!
