Mudrock Soup and Bugs

I'm working on a dish I call "Mudrock Soup and Bugs." I still need the major ingredients, and... well, I don't think I'd last long trudging through Dustwallow Marsh! So, <name>, can you do some hunting for me? First, I need the tongues of Mudrock turtles. You can find Mudrocks along the coast, mostly around the bay. But I don't want just any tongues! I hear that the tongues of some Mudrocks are forked... They say the forked tongues have a distinct flavor, and I want that flavor in my dish...
