A flower-like enemy that first appeared in Kirby Super Star.
Kirby can't inhale it.
In Kirby Super Star Ultra, Rosely exists as an enhanced version of it.
In the Kirby: Right Back At Ya!, she started out as an ordinary flower, but was turned into a hexenbiest by Nightmare Enterprises.
She tried to parasitize Whispy Woods to wither and die or send her calyx flying like a boomerang to take down Kirby.
Kirby can inhale her calyx to gain the Cutter copy ability.
