Marine Observatory: A guide of sorts.
With the new Farm comes the Marine Observatory. This is basically like an Underwater Unicorn Island, or any of the other "Harvest, get something, smush enough somethings together, get a critter" buildings. Spirits, Serums, DNA, Gems, Fishscales, whatever, it gives you a chance to pretend you are a Mad Scientest. Which is not a bad gig from what I hear.
So below is a Chart, that shows the order the animals appear, plus the color of fish scale they should give.
Animal | Color Fish Scale |
So Clearly if you want more of a Specific Color, remove from your Observatory the creatures that give OTHER colors.
