It was a beautiful day in Equestria, and some pony was experimenting with potions. This pony was none other than Twilight Sparkle. As she was carefully trying to pour a drop of solution into the brew that she had been working on for the past month. She leaned in close, as she laid the rim of the test tube, onto the rim of the beaker. Using her magic, she tilted the tube, just as the drop started forming around the rim. She had worked for months on this, and nothing was going to stop her. The drop of liquid was about to fall into the beaker when wiz of blue zoomed in the window. This caused Twilight to jump in shock, she dropped the test tube, and the liquid spilled all over the floor. "Rainbow Dash!" Twilight shouted. "Sorry, I'm trying to practice for the Wonder Bolts," she said. "Well, can you practice somewhere else please, I'm busy," the purple unicorn said. "Fine," Rainbow Dash sighed, starting to walk out. "Wait!" Twilight said. She picked up the beaker. The liquid in the test tube had mostly spilled into it. The liquid in the beaker had changed color. From a light green, to a dark purple. She set it down. Just as Spike belched a scroll. Twi took it, and read it aloud. "Dear Twilight Sparkle. I would like you to try a spell I found. It's easy, but be careful, it's easy to mess it up. Princess Celestia," Twi finished. She looked at the spell. "Rainbow!" She called. "Can I test this spell on you?" She asked. "Sure," the Pegasus replied. "Will it give me super speed? That would be great for the Wonder Bolts," she said, with an, I'm-cooler-than-you smile. "I don't know," Twi said, with an annoyed look on her face. "Okay, zap me," Rainbow said. Twilight cringed, as her horn lit up, a stream of magic shot out from it. Rainbow Dash gasped as the beam stuck her. She felt pain, as her body parts shifted and moved. A big flash of blue, and Twilight looked at what she did.
