Minccino

Black: They greet one another by rubbing each other with their tails, which are always kept well groomed and clean.

White +2: These Pokémon prefer a tidy habitat. They are always sweeping and dusting, using their tails as brooms.

Black 2 +3: Minccino greet each other by grooming one another thoroughly with their tails.

Ultra Sun: A clean freak that will not allow even the slightest mess, it uses its tail like a mop to thoroughly clean any and all filth.

Ultra Moon: When its tail has gotten dirty from self-cleaning or from cleaning its nest, Minccino spends a whole day washing its tail in clean spring water.

Sword: The way it brushes away grime with its tail can be helpful when cleaning. But its focus on spotlessness can make cleaning more of a hassle.

Shield: They pet each other with their tails as a form of greeting. Of the two, the one whose tail is fluffier is a bit more boastful.
