Flavour / Design: Oddish used to be found abundantly in Alolan rainforests until several cataclysmic volcanic eruptions destroyed the forests, leaving Oddish with no home. But the ashes of the burnt trees proved very nutritious, so the Oddish hung around forest fires and volcanic eruptions until they adapted to the surroundings. The grass on its head is replaced by a red-orange bonfire and its colour turns into a deep burgundy.
