A small, yet common yukkuri. Most other species and even humans seem to not notice them, unless of course they find an infestation of Wriggles. This is so far the only yukkuri know to reproduce by death. In the wild, once a Wriggle becomes pregnant, it will die and its koyukkuri, born rather quickly, will eat their mother as a first meal, similar to how other yukkuri eat their stalk as a first meal. This behavior, in yukkuri canon, have become less common in recent years and it's more common for the Wriggle to reproduce by usual methods.
