Мунна

Black: Munna always float in the air. People whose dreams are eaten by them forget what the dreams had been about.

White +2: It eats the dreams of people and Pokémon. When it eats a pleasant dream, it expels pink-colored mist.

Black 2 +3: This Pokémon appears before people and Pokémon who are having nightmares and eats those dreams.

Sword: Late at night, it appears beside people’s pillows. As it feeds on dreams, the patterns on its body give off a faint glow.

Shield: It eats dreams and releases mist. The mist is pink when it’s eating a good dream, and black when it’s eating a nightmare.
