Ignalt eggs are nearly indistinguishable from basalt rocks. The only difference being the moss that grows on Ignalt eggs is more difficult to remove.
Ignalts are self sufficient from the moment they hatch. Unlike many species Ignalts do not eat meat or plants, they eat volcanic rocks instead. Only very young Ignalts are found above ground on the Volcano's surface. As Ignalts age they spend more and more time underground, eventually retreating from the surface entirely. Its rumored that there is a large Ignalt colony deep underground near the Volcano's magma chamber. The Science and Research Center has yet to develop a means of reaching such a depth in order to validate this claim.
The Ignalt's growth cycle is very slow, only an inch max a year. However Ignalts never truly stop growing. They begin their life about the size of house cats and can grow to astonishing sizes. One spelunking team came across an Ignalt and recorded its size to be 13.5 feet tall. A rare occurrence as not many Ignalts are seen once they leave the surface. It is speculated that once an Ignalt descends underground that their metabolism slows down drastically. The Ignalt then spends most of its time in a state of deep hibernation, blending in almost perfectly with the rock around it, and only wakes in order to eat and move further underground.
