Originally poisonous and scary-looking mutant worms that were paper tigers not very powerful. In early autumn, they evolved drastically — their colorful fine hairs turned into sharp spikes, and their heads and tails evolved into gaping maws with no eyes or nose, just round flower-shaped mouths with sharp teeth visible. They look like desert bloodworms brought to life. Their defense seems stronger after evolution though their speed remains fine. They drop glowing fragments including coins, scraps of cloth, unknown-material hairpins, poison arrow pouches, silver needles, and medical syringes.
