Cleffa, the Star Shape Pokémon. Cleffa is the pre-evolved form of Clefairy. Their star shape has led some to believe that they reach the Earth riding on shooting stars. Strangely, many Cleffa are often found on nights of meteor showers.

One of the baby Pokemon introduced in Gen II, Cleffa is the baby form of Clefairy. It evolves into Clefairy by Happiness. Cleffa is pretty cute, it looks like a little star. It also looks kinda like a plushie. In fact, in Pokepark 2, one of the items to make Pokemon happy is a Cleffa doll, which looks like a smaller version of Cleffa.
As a baby Pokemon, its stats are pretty low (HP and Sp Defense being its highest), and it doesn’t learn many moves by level. Most of its moves by level are status moves like Sing or Sweet Kiss. It does learn Magical Leaf for some reason though.
