Seed Weeds are plants appearing in Wario: Master of Disguise. They appear in Ancient Waterworks. They are walking plants with yellow heads. They can shoot out seeds from their mouth, and the seeds quickly grow into another Seed Weed. This is their way of reproducing. Their sub-species are Thorn Weeds, plants created with the Wishstone. They are also created by the boss of the Ancient Waterworks, Ka-Bloom!.
The only thing on this male plant's mind is pollination. He shoots his little plant seeds with reckless abandon in an effort to leave behind as many progeny as possible.
