Story:
Rosa caught wind of a rare Pokemon in a nearby forest. It was rumored to be a Shiny pokemon as well. With high hopes, Rosa marched into the forest without a single hint of fear. As she was searching, she came across a strange looking Pokeball. "Did someone already catch it?" Rosa thought, as she picked up the overly shiny pokeball. She also couldn't shake the feeling like she was being watched. The pokeball looked like a Love ball but it was just way too shiny. She didn't have much time to wonder as the pokeball suddenly opened splashing rubber goo all over Rosa.

Rosa found her hand and forearm replaced with rubber claws and giant puffy arm warmers! Panicking, She tried to remove the yellow arm warmer with all the strength she could muster, but it just won't budge. In fact, the rubber from the thick arm warmer started to spread to the hand she was using to get it off. Rosa looked down to see she was standing in a puddle of brown goo. She found her shoes had be converted into yellow paws! Rosa finally realized that she was turning into a Lopunny! The very pokemon she was hunting! As She was looking down, she saw two large rubber pillars form up from the puddle. These large pillars then shot straight into her ears! She could feel the rubber forcing their way through her ears as it covered her face.

Trying with all her might, Rosa yanked at the ears but they only seems to enter more and more. Her entire body covered in the Lopunny rubber. She felt light headed and then soon felt something else think in her head "We'll make a perfectly good Lopunny, wouldn't we~". As soon as the thought completed, Rosa felt half her body seemed to shut down. Only for it to revive under the command of another entity. She felt the other half smile as it even took control of one of her eyes! "Don't resist, We'll be much happier soon~" said the other personality. Despite her best efforts to resist, all she could muster was a little bit of shaking and twitching. The new Rubber Lopunny turn around to greet the other Lopunnys that were watching the transformation occur. Rosa disappeared into the pack of Lopunnys, with a new goal of making more of them.
