Origin of Garden Fluffies

>As a last-ditch effort to control the explosive fluffy pony population, Hasbio scientists attempted to create something that was harmless to the environment to destroy their great mistake.
>The resulting bio-weapon was based partially on the fungal infection known as "cordyceps", and partially by that old wives tale about swallowing watermelon seeds.
>The vector of infection was simple: Fluffy ponies love the smell and taste of flowers, above all other plant types and materials.
>This plant had seeds which, while not immediately fatal to fluffies, would eventually kill them, and grow more flowers from their fluffy corpses, all while hijacking their nervous system to make them spread out.
>So the initial trial was promising, in a tightly controlled facility, twenty fluffy ponies ate the flowers of the new Bio-weapon, code named "Fluff Garden"
>After three days, nineteen of the fluffy ponies had begin behaving irrationally, going as far apart as possible, delayed reactions to stimulus, craving to eat fecal matter, many other abberant decidedly un-fluffy symptoms and behaviors.
>The twentieth was found to have not consumed any flowers, just stalks.
>She was force-fed flowers and moved to a separate pen.
>By the fourth day, all the fluffy ponies who had eaten the flowers were dead.
>The product was declared a success and immediately seeds were dispersed for field testing.
>The dead Fluffies were disposed of by chucking them out with the garbage.
>By the sixth day, the fluffy mare who had initially not eaten any flowers was showing the exact same symptoms as the other nineteen fluffies had shown three days earlier.
>Her cries for "Moh Wawa!" and "Fluffy wan' SUN!" are ignored.
>It is decided to just clean up her corpse when the researchers get back.
>Having solved the fluffy crisis, they all leave for a celebratory three-day weekend.

>The researchers return on the ninth day.
>The chicken-mesh door to the fluffy's kennel has been torn open from the inside.
>The sinks have all run over.
>The blinds have been pulled down.
>Fake potted plants all knocked over.
>Real potted plants all uprooted.
>Basking in dawn's early light, in the corner office of the head researcher, the fluffy pony lay.
>Her back a mass of flowers, vines, and saplings.
>"I don't want to play now. This is Sun time."
---
>On the seventh day, the nineteen fluffy corpses dug their way out of the trash.
>"This is good. Sun is good for garden."
>"I need more Sun. I will go this way."
>"I need more water. I will go this way."
>"I want better earth. I will go this way."
>And so the nineteen original garden ponies went their separate ways.
>Each carrying more of the flowers that would create semi-immortal zombie garden fluffies.
