Pokédex entries

What each game says about it, in the games' own words.

Black / Y / Alpha Sapphire	Like the wind, it can slip through any gap, no matter how small. It leaves balls of white fluff behind.
White	Riding whirlwinds, they appear. These Pokémon sneak through gaps into houses and cause all sorts of mischief.
Black 2 / White 2 / X / Omega Ruby	They appear along with whirlwinds. They pull pranks, such as moving furniture and leaving balls of cotton in homes.
Sun	It rides on the wind and slips into people’s homes. After it has turned a room into a cotton- filled mess, it giggles to itself and takes off.
Moon	This Pokémon appears, riding upon the wind. But if the wind gusts up, it’ll blow the cotton on this Pokémon’s head clean off.
Ultra Sun	This nuisance sneaks into people’s homes, where it hides important things and scatters cotton all over the place.
Ultra Moon	Whimsicott doesn’t live in a fixed location. It floats around on whirling winds, appearing all over the place to perform its mischief.

Official data here is present-day reference data from PokéAPI, not a snapshot of any one game's era — the Fairy type and hidden abilities arrived partway through the series, so a difference against an older game can belong to the series rather than to that ROM hack.
