Sand Screamer

A mysterious species of Rahi found on Voya Nui that screams in the night. There have been no recorded sightings of the Sand Screamer by a Matoran, and some are not even sure it is a Rahi. However, there has been evidence found that such a Rahi exists. Most of the evidence comes from the corspes of dead Rahi killed by a mysterious beast and tracks sighted near them.
