I love love love the genre of fics about Grace coming to Erid and being mistaken for a pebble so much. It's such a delightful misunderstanding that can be such an interesting vehicle to dive into Eridian culture or the horror of what happened to Grace or to just have some good old crack <3
Anyway, in no particular order, these are the fics about it that I've read these past few days for anyone who also loves these kinda fics! Please do send more recs my way if I am missing out, because there isn't a canon ao3 tag yet (dont be nervous about self promo'ing, I encourage it)

Can we talk about the fact Rocky literally made Grace a crib to sleep in so Rocky could watch him as closely as possible. I don’t care what anyone says this is a CRIB, it’s like one of those floor crib with the lower guard rails and adult sized beds for toddlers so their parents can nap with them. Applying the head cannon that Rocky views Grace as a baby makes this whole scene more funny because of course Rocky would panic when his new toddler human crew mate says he’s going to go sleep on a ship alone in a atmosphere Rocky can’t get to if there’s danger. This toddler who acts stupid when he’s tired and barely even keep himself from bumping into a scale model every two seconds is now trying to sleep BY HIMSELF! Who knows if there is danger on the Hail Mary!? What if he wakes up from a nightmare!? When pebbles have nightmares they need the reassurance of their parents/guardians and Rocky couldn’t get to him on the ship before his Xeonite ball was constructed. So what’s the solution? Well obviously it’s to guilt trip the toddler into sleeping in the tunnel and while Grace gathers his sleeping cushions Rocky will construct a bed-like structure for the toddler to feel comfortable and safe while Rocky watches him sleep and if this structure just happens to resemble a Eridian style pebble nest…well Grace won’t know either way.
That is until they get to Erid and Grace off handedly mentions the cultural differences of human and Eridian sleep cycles and how Rocky essentially made him sleep in the tunnel connecting their ships in this little Xeonite bed Rocky made for him to fit into and the other Eridians look at Rocky like;
Eridians scientist: You made him sleep in nest, question?
Rocky: Yes.
Eridians scientist: He is savior of Erid and you made him sleep in nest like pebble?
Rocky: Yes, because he is pebble.
Eridians scientist: He is pebble, question?
Rocky: He is BIG pebble, statement. Only in his thirties and stupid when he does not have sleep, trips on things, gets cranky, makes work take longer. So Rocky make nest for pebble….was necessary to save stars.
Eridians scientist: Yes, yes, agree.
Meanwhile Grace is off to the side just nodding along not having understood a word of what they were saying because most of the words they’re using aren’t marked in his translators yet. (I also like to think that MAKING the nest is something only a parent or family member does for a pebble, so Rocky making him a nest is the Eridian equivalent of him signing adoption papers and no one questions it.)
Eridian Pebble Shifter AU Masterpost
Welcome to the masterpost for my Eridian Pebble Shifter AU, a spinoff AU of my main Eridian Shifter AU!
In this Pebble AU, everything is exactly the same as the main AU. The ONLY difference is that Grace's Eridian form matches his chronological age, so he's a pebble!
Ao3/Fic Links:
Eridian Pebble Shifter AU Series
Rocky the Pebblesitter (ongoing, incomplete)
FAQ below! (A lot of questions can be answered in the main AU's FAQ as well, so this will be for pebble au specific questions!):
Avatar style Ryland Grace where he's given an eridian body, but it corresponds with his earth years of being alive so his eridian body is only like. 30 years old. He's a pebble in Eridian years.
His amazement and excitement of being in a new body is perceived as childlike wonder. He is THE baby
He's like the size of an egg

Pebble Grace Fic Recs
pebble grace is a trope where adult ryland grace is considered or mistaken as a pebble (child) by eridians. some, but not all, of these can be found under the tag “Adult Ryland Grace is Considered an Eridian Child | Pebble” on ao3
for anyone who loves the “pebble grace” trope, I made a collection on ao3 with EVERY pebble grace fic I could find. I continue to keep it updated as more are published. it’s also open (moderated) to new additions by other users if there’s any I’ve missed
THE COLLECTION: Pebble_grace_fics
My Personal Favs:
they’re also tagged as “fav” in the collection
Babybird (Series) by disasterdrow & Taraxinium — I believe this is the original pebble grace fic that started this trope! It’s a super cute read
Speak to Me by RegtheRag — Pebble Grace + Rocky having amnesia! Fantastic and detailed
Rockabye by Skye_the_Lofty_Nutcase — Pebble Grace is “adopted” by and gets to meet Rocky’s extended family after an accident leaves Rocky unconscious
Speech Pattern by Chaotic_aroace & Lizgir12 — Another really cute take on the trope! Check it out!
PebbleSong by Lure3808 — This one is full of misunderstandings between characters! It’s great!
Hope from the Silence of Space by WolfeOfLullabies — Another great fic! I’m running out of ways to say just how good this is! Love it!
Adrian is a simple creature, they see sad pebble, they adopt sad pebble. by BusyBee — This one focuses a lot on Adrian and Grace. So cute
Okay, I definitely think I'm gonna make my pebble/Eridian Grace an eventual bloodymary thing, but I'm trying to figure out how to do it. . .
Like, the idea I had in mind for Grace reincarnating is that, after trying and failing to have pebbles, Rocky and Adrian decide to bury their more recent egg where Grace was buried (so he can watch over the egg for them while it's vulnerable even in death 🥹), and that's sorta how he becomes an Eridian.
But how would it work for Simon?? Does he just like, die in the sub and wake up in a new world, in a new body? Or should it be that he was already on Erid when he died and came back?
