These eggs cannot hatch due to the Primary Containment Facility being built to match the ideal conditions for an adult Sea Emperor Leviathan, which seem to be significantly different than the ideal conditions for a baby, as a result, these eggs have been in this state for hundreds of years. The eggs are attached to a piece of Precursor equipment that supplies them with what is necessary to keep them alive. The Player must hatch these eggs to cure himself of Carar in order for him to be able to leave the planet. To do so many plants must be gathered to create Hatching Enzymes.
