I find it a bit irritating that S8 gives us such vague clues to go on for collections. Take the hint "From Nature" we have tons of nature items that technically do include animals, rocks, flowers, trees and logs and grasses. Not all of these yield "Star Dust" it only Comes from chopping lots of trees. And the "Moon Stones" that come "From Animals" is even more misleading. I have close to a hundred animals out in my kingdom and a zillion more in inventory ( growing by 10 pigs from quests pretty often). I have cats, dogs, cows, pigs, horses, chickens, sheep, alicorns, manticore, dragons, Griffins, nagas, a camel , a skunkupine and a mythical Pan. With all these animals you would think gathering the Moon Stones would be simple, but no, any specialty animal does not count so good bye all cats, dogs, alicorns, dragons, manticores, Griffins,nagas, the camel, the skunkupine, the Pan and any holiday cow, rsheep, pig or chicken. So you have your regular farmyard animals, right? Cows, pigs, chicken, sheep and horses nothing fantastical, cool. But no, for some reason I have not gotten a single Moon Stone from a single sheep or horse. I continue to try in case I have just have the worst luck ever, but why can S8 not just tell us straight up. . . Check trees for star dust, check cows, pigs and chickens for moon stones? Why does everything have to be a big secret?
