@Teneo oh wow, now that's a find! that there looks real like those cute sea slugs out there, funny enough! Definitely a common color palette i've seen in fandragon searches on FR too!
hm now here's where it gets tough- the only near-double double i've seen on sale was my own, which was also pastel, that i traded for a four digit. But i've also seen some close misses for as cheap as 10MS, even though it could very well be the newer players who hadn't noticed.
Yours is definitely a good one! It might take a while for a sale, considering pastels are going faster than bright colors atm, but considering the rarity of blue-yellow wolves on sale, i'd say 150 to 500 MS price range would be good enough!
But you would have to consider that a lot of people have spent a lot of moonstones in the past month (and that its so hard to get ms without paying atm) and dens are getting full, which is why sales are going down too rn. So it might take a bit! but if you hold out, you should get what she's worth.
(also psst i think you were looking for a bracc scroll? someone's selling for gems in the forums, but idk if it's sold already or not)
