I never thought much about why those bubbles appear. I guess air is stored down there. And about the Giggi. I always thought the Gigginox migrates to the other biomes to reproduce. The fact that Gigginox can give birth while IN THE MIDDLE OF A BATTLE suggests they do not need to mate to produce a new generation. They may as well have a special organ that produces eggs when they want too. Also I think it would be fairly hard to find a mate in those dark caves, so this might just be a special adaptation. The reason you never see Noxs outside of the Tundra is because they spend much of their lives there, only migrating occasionally. Also I think Noxs are terrible parents. Sure they may protect their eggs from predadors, but they appear to use their offspring for protection other than anything. Just a thought tough. We don´t see much of the parenting skills of monsters.
