Original Description:

Blossomforth is enjoying a peaceful day in the wilderness gathering flowers and enjoying using her alien body. Living in a pony body most of the time to fit in is so stiff and confined compared to the freedom she experiences alone out in the wilderness as an alien shapeshifter. She experiences much more strength, flexibility, and adaptability than she would otherwise. In her relaxed state, the tentacles that previously behaved like spider legs (>>3379352) turn into completely flexible ropes of flesh. Mother nature conspires to make her even more relaxed, enjoying being outside in the sun. It’s nice to forget about her responsibilities as an advanced life form and instead enjoy the moment. One of her tentacles has morphed into a pincer appendage to pick a flower. Because it has recently transformed, the skin surface area has increased without enough time for thicker skin and white fur to cover the recently shapeshifted flesh, giving it a more reddish hue.

Thanks to Mutter for doing such a great job drawing BlossomThing! Blossomforth is a character from the show but I wrote a fanfic about her, imagining what it might be like if a pony like her had gained incredible alien shapeshifting abilities.
