After using its other-worldly form to assimilate the biomass of Amber Rose, The Thing finds itself taken to the outside of Canterlot High by her shape's normal routine. It is ready to enter and begin the process of assimilating other biomass and spread itself like a virus across the world.

However, little does it suspect that there is another existentially horrifying insidious plague waiting to infect it within those High School walls.

Converted from a greentext story I wrote for the /trash/ MLP Bimbo thread.
Set in the Annonverse, a universe where CHS is saturated in bimbo magic.
