Rainbow was flying around Ponyville, issuing orders to a couple of pegasi for the downpour this afternoon. She was waiting for this downpour for a while, and told the pegasi to leave a small area un-clouded so she could practice her Sonic Rainboom. She wan'ted to master it, even though she knew that at the Royal Wedding she did it in about 2 seconds, doubling or tripling her speed. Twilight did scientific studies and told her she got about 20% Cooler, or Faster, in 10 seconds flat. She wanted to get about 200% Cooler in 10 seconds flat, so she was practicing. After the ordering, she stopped in a nearby tree in Sweet Apple Acres and prepared herself for a nap. A small patch of clouds was nearby, so she decided to play a prank on that pony that was below her. She could at get some laughs by cracking a patch of clouds to the hiccups, like she did with Pinkie and Spike. She the cracked the cloud as loud as she could, and begun to laugh. "Ha ha! Good one, RD!" Rainbow Told herself, crying from laughter. But then she noticed she never saw this pony before. It was a dark blue unicorn with wavy hair. Oh, and creepy green eyes that didn't have little white dots. Oh look, Rainbow is proceeding to laugh even harder. She leaned her head out, tears still in her eyes. "Who-HA!-Are you?"
