been collaborating on likeeeee, OC relationships with Mango involving some other artists' OCs and in that process I developed the idea that "Mango Shores" was not Mango's original name,,, I landed on his birth name being Gold Rush. :) we'd been developing his family heritage, the rough idea being he comes from a family of like prosperous business/farmer pegasi. I like to think waaay back in his family tree before they were rich and successful, they came from humble pegasus farmers with maybe some earth pony genes in there. So his parents and siblings are all pegasi and he's the only flightless one. 🥀
but anyway as i was pondering how/why he'd eventually change his name, i fell in love with this idea that like, he's the black sheep in the family already without even trying, hasn't found his special talent yet,,,,, his family travels a lot for business and overseeing their farms by flying and he has to get transported separately because of it, and i think one time while traveling via boat he gets lost at sea. he ends up on this deserted island which is a totally new experience for him, growing up spoiled, but finds he thrives in this natural environment and would eventually get his cutie mark here ((if i wasnt lazy at designing cutie marks lmao)) his talent involves living off the land, and drink mixing. :)
while he's on the island he befriends a little shell-less hermit crab he names Rita later on, and she becomes his little drink mixing buddy hehe.
his family finds him after a while and he returns to his old life somewhat reluctantly,,, but likely as a teen or adult he chooses to leave and return to the ocean to start his life.
