There's Music in Us.

-Grace did not design the body himself, but was encouraged to pick a phenotype to grow it from so he opted for an orange colouration and the genetic traits that came with it. The science behind growing the body was based on the me-burger experiments.

-The body was grown to be older than Grace’s human age to make sure he would still be seen as a mature adult, but he’s still somewhat younger than Rocky.

-He requested having the scar of Rocky’s handprint tattooed onto one of his arms.

-He struggled with finding his balance and voice at the start, and grew a bad habit of not fully using the mobility of his fifth limb, either slightly dragging it or keeping it raised and out of the way. This resulted in a lot of tripping and stumbling but he figured it out eventually! …Mostly!

-He was able to pick up the language pretty fast since he was already familiar but his voice remains pretty “flat” sounding to other eridians. This is a somewhat uncommon but not rare speech impediment on Erid, akin to human stutters, so he gets by okay and most eridians might just struggle reading his emotional tones until they get used to it. At the start this made him hesitant to use his voice but Rocky and Adrian were quick to encourage him into several scientific yap sessions to make him more comfortable!
