Starlight vs. Cozy Glow (and her marshmallow clone army)... It's going to be messy and weird, but she's ready for that.

Contains more than the daily recommended amount of bladed weaponry, unnecessary explosions, shipping, and butt humor.

Also an entry for https://www.fimfiction.net/blog/1019523/cozy-glow-short-story-contest-4, under the vs. prompt.
