These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ugly Cute: Demon larvae. Centipede-like critters the size of a young pony with lots of legs and occasionally wings. Drawings of them cause nearly the entire forum to break out in choruses of "D'aww..." Special mention goes to Budgie, who is infamous diabetes material.
Also arguably Patchy, who is a tiny foal made of corpses.
