The Fungus Cone

High in the tower Koopa entered a room where a large bulb of yellowish let yellowish fungus hung from a fungus enveloped deevolution cone. That doesn't happen in the book. I guess it's implied that it could happen because you can evolve people as well as deevolving them. There's something weird where just like Bowser dying just causes a bunch of stuff to happen. Now like there are I'm finding fungus balls but they just look like a like a flower ball or something.
