The best way to describe FishVille's new Discovery Log is to call it the most sophisticated achievements page for a Facebook game we've ever seen. It makes players utilize every function of the game in order to complete collections. The Log keeps track of fish and treasures, but it's also a platform from which you can collect the stuff you need. For example, clicking on the item listed allows you to go straight to the action required for obtaining said item. But it's only that easy if you do the Sand Dollar method, which is simply ponying up real world cash.
Below we've got a list and tips for everything you need to know to get all your treasures. The easiest thing you can grab is the "Deep Sea Coral," but it's going to cost you 56,250 Coins.
Mermaid Statues: Mermaid Maiden, Merman Minstrel, Mermaid Queen, Merman Soldier, and Dolphin Princess
Tip: Buy with Sand Dollars or find them inside Mermaid Mystery Boxes, which are free gifts. They're NOT on the Free Gifts page. Instead, click on the listing to send the boxes to friends.
Precious Shells: Blue Shell, Pink Shell, Purple Stombus, Spikey Shell, and Wavy Shell
Tip: You can get these only by redeeming "Fish Love". This involves regularly feeding and caring for your fish. When you do, you can collect their "Love" and buy items with it. For more info, please read the Fish Love guide.
Deep Sea Fauna:
Bamboo Coral, Bubble Gum Coral, Deep Sea Coral, Gibsmithia, and Picasso Sponge
Tip: Grab the Deep Sea Coral at the store for 56,250 Coins, but you've gotta look at the "Deep Sea" or "Decor" section, as it won't be under "Plants". The first two items can only be found by collecting enough "Nautilus Shells" from friends. There should be a "Nautilus Shell Stash" icon on the lefthand side of your game window. Click on that to learn more. The last two coral pieces are on the Free Gifts page.
