Whats a Maru Mari?
Maru Mari is the name of what is now known as the Morph Ball in Metroid 1. As told by Nate, “very hard to translate without using another foreign language you’re probably not familiar with. basically if you think of the word ‘processing,’ as in to move from one state to another, and then you thinking of the word ’rounding’ in a transitive sense, i.e. ‘to be processed into becoming round,’ you can get a feel for what it is.” So, in short, Maru Mari means “to be morphed into a ball”.
