Lizard Fossil (Japanese: トカゲの化石Lizard Fossil) is a monster that appear in the Underground Maze of Neksdor. They're fairly weak, but tend to be accompanied by other monsters. Defeating this monster rescues a Mii's pair of eyes.
Sometimes accompanied by Yellow Cobras or other Fossils when encountered.
It looks like a green slab of stone with a small, skeletal lizard fossilized inside. It has two Mii eyes on the top of the lizard's head.
