Cottonee
The Cotton Puff Pokémon
Type: Grass/Fairy
Official Registration #: 546
Entry: Cottonee are small, fairy-like pokémon covered in a thick layer of cotton puffs. These cotton puffs are essential to its defense mechanism, as when threatened, it will launch clouds of cotton at the threat in order to confound them as it gets away. This may seem like a weak defense, but never make the mistake of underestimating it unless you, too, have been buried under a mountain of cotton launched by a full flock of cottonee in the wet heat of an Unovan summer day. For those uninitiated, imagine being set on fire. Now imagine that you’ve been set on fire by a minimum of fifty pounds of solid flames that you must wade through in order to not be on fire. This is what a cottonee spray is like.
Whimsicott
The Windveiled Pokémon
Type: Grass/Fairy
Official Registration #: 547
Entry: The evolved form of cottonee, by exposure to sun stone. This adorable sheep-like pokémon may seem whimsical and innocently playful at first glance, but never take your eyes off one or catch one’s interest in the field. They have the ability to compress their bodies and wriggle into homes through even the slightest cracks, where they will proceed to rearrange the occupant’s possessions and leave cotton wherever it goes. As a related note, after extracting a whimsicott from your home, always do a thorough check of every possible nook and cranny of your living space for any stray cotton. Cotton, after all, has an uncomfortable habit of clogging toilets, choking air vents, and generally being highly flammable.
