Day 71: Steel Eeveelution
A particularly rare eeveelution in the wild, Eevee become capable of evolving into Ferreon after being coated in a layer of metallic dust. While this would be harmful to most creatures, Eevee just does what Eevee is apt to do, and incorporates the metal into its own fur, producing rough, wiry hairs that are sharp and abrasive to the touch.
The changes to Ferreon are deeper than just some new fur, though. Upon evolving, Ferreon’s mouth and digestive tract all but disappear, and instead it begins to feed by absorbing more ferrous powder through its skin. As metallic dust is unexpectedly hard to find naturally, Ferreon is capable of releasing a mysterious gas from its ears, capable of quickly oxidizing surrounding metal and reducing the now rusty mess to powder. For this reason, Ferreon are intensely feared by other Steel type Pokémon, and it is highly recommended that any trainers actively separate them.
To keep its own fur safe from rusting, Ferreon constantly preens and coats itself with an oily substance that it produces from the area where its mouth formerly was. Despite Ferreon’s destructive potential, they are frequently raised to harvest this oil, which can be used as a remarkably strong sealant.
One of Ferreon’s abilities is Rough Skin, though I am not yet certain what the other would be.
