We got that uber "you can open clams while flying" fix a patch or two ago and look what's in the 3.1 PTR patch notes:

(I'm not making this up)

Clams

• A new clam, the Giant Darkwater Clam, can be obtained by fishing in Wintergrasp. This mighty clam has a greatly increased chance to drop pearls, and yields up to five times the regular amount of clam meat.
• Loot from clams now stacks correctly!
• Changed the icon for Succulent Clam Meat so it doesn't look quite as disgusting.

So who did Blizzard recently hire that is obsessed with clams?!
