>>20293524Marill is Fairy type for a mythological reason. Have you ever heard of Moon Rabbits from Chinese folklore(Azumarill's animal base), the moon's association with the oceans tides(which explains the water typing) and the white elixir of life the rabbits constantly create for the moon goddess Chang'e
(Azumarill's white bubble pattern)? Azumarill appears to be a combination of all of those. Which is why it was suited to have the Water/Fairy combination.
