"Finally!" Rainbow Dash had just finished up her job for today. Busting clouds and setting the town up for the storm this afternoon. "Whoo! Finished! Let's see what else I...gotta...do. Ohh." She was going to start on another job she was told she had to do, but when she looked up, it looked like she had done everything she was supposed to. "Guess I really did finish. Welp! Time for my chore! Naptime for Rainbow Dash!" Rainbow plopped herself on the nearest clean, white cloud and curled up in a ball, about to go off into a deep, peaceful sleep. "*Gurgle*" Dash's eyes snapped open at the sound of growling and immediately shot to attention. "Who's there?!" Rainbow searched wildly for the source, but only saw an empty dark cloud-covered sky. "Show yourself!" There was a gurgle again, but this time Dash looked down and saw that the culprit of the noise was not a hungry monster, but her hungry tummy. "Ohh. Glad nopony saw that. Speaking of food, wonder if Applejack still has some grub in her cart?" Rainbow made to fly to the ground, but instead decided to do the 'fun' way. And with that, she snapped her wings to her sides and began to plummet down to Ponyville.

The ponies in Ponyville always overreact to even the smallest bad thing. Passerbys who heard nothing would go about their own business, ponies who likes to get a quick drink from the local water fountain would think they heard the sound of a falling object and when they'd look up, they'd be right. When some points looked up, they overreacted, which cause panic around. This is called a domino effect. Ponies started to gather around the fountain target, but soon got worried when the falling figure came slightly into focus, just enough to see what it was, not who.
