The trainer on Route 209 has Cleffa in Pokemon Platinum. Cleffa is a fairy type Pokemon and can evolve into Clefairy.
Cleffa evolves by happiness. She doesn`t evolve by a certain level.
It does not evolve at a certain level but Cleffa evolves into Clefairy when you level it up when it has high friendship. It then can evolve into Clefable when exposed to a moon stone. Happy Pokemon Catching J.R.
