Ooze

General
The Ooze is a mysterious NPC that appeared in Kamadan, Kaineng Center, and Lion's Arch before the release of Guild Wars: Eye of the North, along with Rats. The Ooze cannot be interacted with in any way, and follows a set path.

Visually, the Ooze resembles a blob of liquid. It occasionally pauses to reach tendrils up into the air, then resumes rolling.
