Pink Smogling
A Pink Smogling (ピンクロ, "pinkuro") is a version of the Smogling encountered after beating the game, no longer evil due to being controlled by Miasmo . They transform regular flowers into Rainbow Flowers the same way a regular Smogling changes a flower into a Black Flower.
Defeating Pink Smoglings
Although they are not detrimental to the park, but in fact make the flowers there more valuable, they can still be defeated in the same way as a regular Smogling; plus the ability to beat them using the Boom Box.
