Here's some rare pokémon, Clefairy and Clefable! They're both the first nocturnal pokémon and the first fairy types I've reached in this challenge. Not that they were 'fairy' types back in gen 1, since it was introduced in... gen 3 I believe. They're normal types in the older games.
I discovered while looking up their traits for the pictures that Clefable can walk on water!
