Unstable Egg

The Unstable Egg is an egg from Egg Hunt 2017. It is located in Mount Ignus. This is one of the hardest eggs to get in the Hunt. You need to find a Green-shirted NPC next to a cave. Go inside the cave, and go down. You will realize that the floor is rumbling, and then lava will start rising very fast. Reach the end to get the egg.
