Ys I and II ChroniclesEdit
A beast guarding one of the sealed Books of Ys. Wriggles wildly, charging intruders. The only way to defeat it is to avoid its speedy attacks and strike its joints before it slides too far away.
A huge, wormlike creature that rules over the Flooded Prison tier. Its tough head is followed by many segments, with countless skittering legs. In addition to the threat of trampling, it also spews bolts of electricity.
