Eggs

Each monster's egg, called spores in the files, is uniquely identifiable, even before the egg hatches. Since each monster in the game is also made from a unique combination of elements, these eggs also represent the 'genetic material' of the two parents shown at the top of the breeding structure. The Kayna doesn't have an egg; its egg only appears in My Singing Monsters: Dawn of Fire.

All Rare monsters have the same eggs as their non-Rare counterparts.
