You caught a Clefairy!
Clefairy (ピッピ, Pippi) is a small, bipedal Pokémon. Clefairy appears to be a pink creature, with stocky limbs and a round body which gives it a chubby appearance. It also possess large sensitive ears that have brown tips. It has small wings that seem incapable of flight, but allow it to bounce gracefully, and when store moonlight in their wings, allowing them to float in midair. Clefairy was chosen as the main character of the Pokémon manga to make it more engaging for readers. However, Pikachu, who was chosen as the anime mascot, became the mascot for the whole series in order to appeal to younger female readers and their mothers. Clefairy evolves into Clefable by giving it a Moon Stone. The Clefairy family were originally Normal types, but in Generation VI they lost the Normal type and became pure Fairy types instead. The same thing has occurred with the Snubbull family. However, the Clefairy family still has the large move pools associated with the Normal type. Clefairy appear in all entries of the mainline Pokémon titles. They also appear in spin-offs such as Pokémon Stadium and multiple entries in the Super Smash Bros. series.
Clefairy’s first anime appearance was in Clefairy and the Moon Stone, in which Ash and his friends meet a group of Clefairy at Mt. Moon, where they pray to a moon stone. It has appeared in subsequent episodes of the series. It also makes appearances in various Pokémon manga series. A timid, shy Clefairy is among the main characters of the Magical Pokémon Journey manga series.
IGN editor “Pokémon of the Day Chick” called Clefairy an “ever-popular Pokémon,” though not as much as in the United States as it is in Japan. She added that she did an article for Clefairy solely because of her dislike for Clefable, though stating that it’s “cool enough.” GamesRadar editor Carolyn Gudmundson compared Clefairy to Jigglypuff, stating that it is far less utilized, in spite of the fact that was initially supposed to be the mascot of the series. She also noted it as a part of an overused Pokémon design, the “huggable pink blob.”
