Sand Screamer

Sand Screamers were a mysterious species of Rahi found on Voya Nui that screamed in the night. There had been no recorded sightings of the Sand Screamer by a Matoran, and some were not even sure it was a Rahi. However, there was evidence found that such a Rahi existed. Most of the evidence came from the corspes of dead Rahi killed by a mysterious beast and tracks sighted near them.
