#i know this post is supposed to have a sexual connotation but imo they're getting weirder than that#rocky lets grace observe his entire digestive process with an adapted x-ray machine#they make some slapdash endoscopy equipment so rocky can look down grace's esophagus and stomach#grace lets rocky pull a tooth for study because he's fascinated by the human body producing something that's similarly sturdy#to himself (also he wants to have it professionally embedded into his carapace as soon as they get to erid but shhhh)#rocky chips off pieces from his own mantle (his deformed legs are already brittler than the rest of him so it's not like it's hard)#also for “study” but is internally debating himself on how to ask grace if he's ever considered subdermal piercings#grace gives himself multiple surgicial lacerations so rocky can get a better view of his sinew and muscle#and document the (from his mostly inorganic perspective) insane restorative ability of human skin#maybe grace even lets some of them get infected on purpose so he can show off his immune system#anyways that being said#rocky is not a biologist and probably doesn't know the exact chemical make-up of his internal tissue.#so they're definitely shoving a heat protected spectrometer up his cloaca

I had a thought: At some point Grace lets Rocky listen to human music, and Rocky gets confused because some of the chord progressions and rhythms mean something in Eridianese. However they just mean straight gibberish with some human words in the background.
