Pippi

Clefairy is very shy and rarely shows itself to humans. On the rare occasions that Clefairy comes down from its mountain home, it can be seen dancing underneath the full moon's light. The area surrounding their dance is enveloped in a magnetic field. Once the sun rises, it returns home, where it sleeps nestled with other Clefairy. There have been many sightings of Clefairy during the morning aftermath of the full moon. In the Pokémon the Series episode Clefairy Tales, Clefairy is depicted as an extraterrestrial Pokémon. Clefairy is known to be popular thanks to both its adorable look and behavior. As mentioned in Pokémon Sleep, anyone who sees a Clefairy using Metronome while sleeping will receive happiness.

This sighting is considered to be a very unusual sight to witness.
