you are in the Engulfed Castle, on its final sublevel. This time, the Waterwraith doesn't seems to be in this sublevel, fortunately. You finds two purple candypop buds. Throwing your Pikmin into them, it closes before ejecting 5 purple Pikmin seeds. Plucking them, you discovers yet another new Pikmin type, the Purple Pikminz it lifts and stomps on foot like a sumo fighter before doing a somersault, creating a shockwave. They seem to be really heavy, and strong. They look at you curiously.
