What bipedal, pink Pokemon can be found in "Pokemon GO"?

The bipedal, pink Pokémon found in Pokémon GO is Clefairy.

Clefairy is a Fairy-type Pokémon introduced in Generation I, first appearing in Pokémon Red and Blue. Its round, pink body, pointed ears, curled forehead tuft, and small wings make it one of the series’ most recognizable early Pokémon. In the Pokédex, it is classified as the Fairy Pokémon and evolves from Cleffa when leveled up with high friendship.

Clefairy is closely associated with the moon. Pokémon stories describe groups gathering under a full moon to dance, and its wings are said to store moonlight, allowing it to float despite not being capable of true flight. A Moon Stone evolves Clefairy into Clefable.

Players can encounter Clefairy in Pokémon GO, where it has appeared through wild encounters, events, and other rotating features. A common mix-up is Clefable, its evolved form: Clefable is also pink and bipedal, but the question’s standard answer is Clefairy. Cleffa, meanwhile, is the smaller baby Pokémon in the same evolutionary family.
