Seed Weed

Seed Weeds are enemies found in Wario: Master of Disguise. They are walking plants with yellow seed-like heads. They appear primarily in the Ancient Waterworks, but can also be found in Sneezemore Cave during the second special episode.

Seed Weeds shoot out seeds from their mouth, which quickly grow into other Seed Weeds. While the enemies themselves are harmless, the seeds they shoot can hurt Wario before they grow. Ka-Bloom!, the boss of Ancient Waterworks, can also create Seed Weeds. Wario can inflict damage on them using any attack.

In-game description
''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.''
