Dive Deep into Creativity: Discover, Share, Inspire
So in the Phendrana Drifts area of Metroid Prime, you explore various areas in the snowy region of the map. There are various sealed courtyards, underground Space Pirate facilities, Chozo temples structures, and ice caves. You also see various creatures, such as various adaptations of other creatures to this cold environment. The most prominently featured of these creatures is the juvenile and adult Sheegoth, a massive predator that dwarfs even Samus. Naturally, these creatures would require copious amounts of food. However, the areas we find them in are sealed enclosures, offering no way in or out besides doors which are too small for even the juveniles to fit through, and which often require specialized beam types to open. So how do these titanic creatures survive in Phendrana Drifts.
While I imagine they are adapted to going long times without food, I imagine these creatures stalk the frozen wasteland above the crevices of Phendrana, delving in to feast on the various micro ecosystems formed in those contained environments. Sometimes, these crevices prove too difficult to escape from, so they enter a hibernation state to conserve energy, waiting for any signs of prey. This explains the accumulations of snowfall that they shake off when Samus approaches.
Additionally, I believe the juveniles tend to stay together until they reach a certain level of maturation. They never seem to appear without another close by. They even seem to use pack hunting tactics to overwhelm prey. Though, this raises a serious question. If the juveniles, big as they are, need to travel in groups and form ice shells over their backs, what else is in Phendrana Drifts?
