Lava Rat

The Lava Rat was a small rodent Rahi that inhabited the island of Mata Nui after the Great Cataclysm, specifically the volcanic Ta-Wahi region. It was immune to being burnt by fire and was known for its ability to spontaneously burst into flames. An old Matoran legend tells the tale of a lava rat trying to get across a body of water on the back of a Takea shark--both were uneasy, because the lava rat was afraid the Takea would eat it and the Takea was afraid the lava rat would burst into flames.
