Clefable is a tall, pink Pokémon with a body that vaguely resembles a star. It has long, pointed ears tipped in dark brown and black, oval eyes with wrinkles on either side. A curled lock of fur dangles over its forehead, similar to its long, tightly coiled tail. On its back are a pair of dark pink wings, each with three points. Its hands have three fingers each, while its feet feature two clawed toes and dark pink soles.
Clefable is known for being timid and nocturnal, fleeing at the slightest sign of human approach. It is one of the rarest Pokémon worldwide. Its sensitive ears can detect even the faintest sound, such as a pin dropping from half a mile to 1,100 yards away. Due to this acute hearing, it prefers quiet, mountainous regions where it feels safe and protected. Occasionally, it has been spotted near deserted lakes during full moons. Clefable can walk on water using a bouncy gait and sometimes appears to fly with its small wings. The anime suggests that Clefable is an extraterrestrial Pokémon. Tradition holds that seeing a pair of Clefable guarantees a happy marriage. Some scientists speculate that Clefable's intense gaze towards the moon indicates homesickness. There is also a legend that says Clefable listens for the voices of its kind on the moon during clear, tranquil nights.
Before Generation V, Clefable and its pre-evolved forms were the only known Pokémon capable of having Magic Guard as an Ability.
