Whimsicott is a small, brown bipedal Pokémon. A mane of cotton-like fluff covers its back, neck, and forehead. Behind it is a green, star-shaped section similar to where a stem or vine meets a fruit or flower on a plant. Whimsicott's face features orange, oval-shaped eyes and its face is flanked by a pair of green-colored lobes shaped like curled horns or ears. Whimsicott can manipulate its body to pass through cracks, no matter how narrow. It takes advantage of this ability as a notorious prankster, moving things and leaving cotton balls behind.
Despite weighing 14.6 lbs (6.6 kg), Whimsicott appears capable of "riding upon the wind" but whether this means they actually generate whirlwinds themselves or get carried by wind currents remains unclear.
Eight Whimsicott appeared in Securing the Future!, with five under the ownership of different Trainers and the rest being wild. They joined the rest of Alola in showering Necrozma with light so it could return to its true form.
Ever found a white ball of fluff you couldn't quite explain? That was likely the work of a Whimsicott. Slipping through the tiniest of cracks like the wind, they like to move furniture around and leave little fluff balls all over the place. Though they look like sheep, they're actually Grass types, and their fluff is more like cotton than wool.
This Pokémon was unavailable prior to Generation V.
Whimsicott's appearance alludes to a fully bloomed ball of cotton but its behavior as a windswept wandering plant seems to be based on tumbleweeds. It also may draw some origin from the Vegetable Lamb of Tartary, a mythical "sheep-growing" plant used to explain the production of cotton in the Middle Ages. This association with sheep is reinforced by Whimsicott's inclusion in the Unova horoscope. Furthermore, Whimsicott displays a mischievous side akin to impish creatures from folklore like the Brazilian Saci; both are brown creatures that live in forests, ride on winds, and play pranks.
Whimsicott may be a combination of whimsical or whimsy and cotton.
Elfuun may be a combination of elf and 風 fū (wind) or typhoon.
