Clefable still strongly resembles its pre-evolutions, but is noticeably much taller while still retaining its vague star shape. It remains a tailed biped, but its ears are now much longer and almost completely the same color as its body, with small brown tips. Its wings are now much larger and a deeper shade of pink, but they are incapable of flight. Clefable loses the elongated left canine and the nails on its fingers that it had as a Clefairy, but gains an extra clawed toe on each foot. The undersides of its feet have a circular dark pink pattern.
Clefable are most known for using Metronome in order to execute a random attack. Just like its pre-evolved forms, Clefable is very versatile whether it knows Metronome or not. The flavor text for Clefable states that its sense of hearing is so strong that it can hear a pin drop from half a mile (one kilometer) away. With its bouncy step, Clefable is even able to walk on water.
Clefable are extremely shy, even more so than Clefairy or Cleffa. As such, they are quite reclusive. It may visit lakes when the moon is present, such as when it is drawn by the full moon to play at deserted lakes, or to take strolls on them on quiet, moonlit nights.
Clefable is just as rare in the wild as its pre-evolutions. They can be found at Mt. Moon, or in other mountains that offer clear views of the moon at night. It is said to be one of the rarest Pokémon in the world.
