“Here we have Fluttershy at her home currently experiencing an astonishing transformation happening to her as she is transforming into her werepony side “Timberhowl” As she watches herself getting larger and larger she could help but have a slight admiring feel as her growing body began breaking through her clothing, Fluttershy couldn’t believe the strength growing in her as it happened.. Luckily she was advised by Twilight Sparkle to wear something that will keep from being destroyed. You’re possibly wondering how it happened, well an encounter with a wendigo caused it after a wendigo spirit went into her, Twilight defeated the wendigo spirit however a fragment was still stuck in Fluttershy so she would become something like Werelight Shine.”
 
Another Request from a Advanceddefence livestream that happened just recently this time featuring Fluttershy getting the “Twilight Unbound” treatment of becoming a werepony. well a more humanoid version mainly but still you get the idea.
