@the-fledgling-artist, oh, that creature does look adorable. You could name the creature a Whapendro, Snowraker, or Moonskipper. And if you wanted, you could have the creature go searching for diamonds, making little dances and mimicking human voices, stare into the moon at night, roll in snow, or any or other interesting fact about the creature.
I’m about to write this story where I’m going to have a lot of made-up animals.
As for the culture, I might have to think about that a little bit myself before I can give you any suggestions.
