Twilight was walking through a jungle that was somehow next to the Dragon Lands.
She looks up at the night sky and remembered what Princess Celestia told her.
...
"Take these, Twilight. These Primal Power Stones will help you on journey."
Twilight looks at a green circular pill with a yellow color in the center of it. "It's a pill?" she says dumbfoundly as she raises her right eyebrow.
"Take the green one to help grant you power unlike anything before, and this red one to help return you back to normal."
"Back to normal?"
"No time to explain. Take it now."
"Okay," Twilight said and she uses her magic to put the red pill into her saddlebag. "Here goes nothing," she said as she uses her magic to levitate the green pill from her right hoof and into the air. Then, lunges her head forward to put in her mouth. Next, with a levitated body of water, she drank it from the air, signaling her that it fell down through her throat.
...
"I wonder what kind of power this magic does. Maybe a mana boost?"
Twilight heard noises from the bushes and out from the bushes were 10 wendigo frogs. And they started running at Twilight.
Twilight pulls back and brings her hooves in front of her. Then, her heart started beating faster. The creatures stopped and watched Twilight go through a change.
"Eeeeyaaaahhh!" She screamed in pain as she felt pain like never before. Her left hoof was cracking and blood splurted out everywhere, and started to sprout wolf-like paws and fingers with super long, razor sharp claws. Her chest started grow brown fur and increases in muscle mass in a female way. Her tail started to grow more longer and furryier as it turns black. Her wings started turning black and turned into furry wings. Her teeth started cracking and falling out as fangs started popping out from her gums as her muzzle turned into a snout. Her horn remained, but curved itself like a rhino horn while red veins started to surround her irises and pupils while her mane turns black. Then, with a strong blink, blood splattered everywhere and her eyes turned yellow. She felt both her forelegs and her hindlegs become arms and legs as they started to become more muscular. She stood up, then pushed her torso forward a little as a lot of black popped out from her back like a giant hairdo.
Whatever she went through... was over.
And now, she feels like her anger has risen. And not only that. But she felt hungry.
Really... HUNGRY.
