Exploring Eridian’s biology. Most of it are taken from the book, but I want to add to it :)
-Rocky and Adrian had kids before Rocky went away. They are now in their (human equivalent) 20s.
-Adrian and Rocky used to be around the same age, now Adrian is MUCH older.
-Baby Eridians are called pebbles (like baby goats are called kids). Yes, this is all Grace doing.
-Eridan’s eggs are like geode.
-Eridian’s eggs (canonically) are laid together when mate and then merge. I however, also think that they would usually go for two at a time for protection (they can watch each other sleep as they get older).
-Rocky name his two new pebbles after Grace and the Hail Mary.
-I’m not a geologist and very much not knowledgeable about rock, but I believe that the green/blue we see Eridians have (movie ver) could be caused by the various level of metal element on their rock layer, like copper and bronze, interacting with the elements over time (Verdigris).
-Baby Eridians are smooth rock. As Eridians grow, they became sharper and more complex looking, caused both by natural aging and external elements.
-Most elder Eridians are green/blue since it’s a form of rusting, kind of like human with grey hair.
