My first version of this round was a bit harder, so send your thanks to @Mick for his suggestions that contributed to making it solvable!
I wanna see the first version to see if I think I would've gotten it (I figured out to look for her color almost instantly, and eventually settled on the icon itself after a bit of testing between both it and her model itself, in case it was something like "find the spot that has most of her model's rendering colors". I actually didn't even notice graham's head was his nh icon until some time after submitting)
also idk if they were hints but other funny bits to point out are kapp'n ("matey"="m8[[y]") and the location coordinates themselves can serve as a silly sort of hint, I guess ([M]arina [8] tentacles, because octopus)
