Unlike Deinonychus Nest however, it is surrounded by lava, which hurts anything that is not immune to it.
It is currently the only nest that is made of make-shift cooled lava and mud with pockets of lava between, as opposed to the withered twigs, leaves and hays (and other decoration like bones and rocks) used by the other 3 for their nest. It is also the only nest that usually have more than one egg.
