I'm currently working my way up in Summoning (finally) and have hit the point where I need 'Thin Snail' meat for the secondary ingredient. I saw where it was supposed to be dropped randomly by just about any snail, so I went after them. After a half-hour or so I realized I must have been doing something wrong, as all I got were "lean" or "fat" drops. I thought to give it one last try in a different area and discovered that I was getting the "thins" that I was looking for one right after another! Turns out that if I hung around the southern end of the bridge on the way to the ferry boat, there were more of the "Myre Blamish Snail -2-", specifically the level 9 ones with 80 life points. I concentrated on these, and found that without fail they would drop the 'thin' snail meat I was looking for. One thing to note, however. They look almost exactly like one or two other snail types, and to make sure you are targeting the right type, you need to right-click any given snail and make sure it is a MYRE blamish, and not one of the others, which apparently will give the other types of snail meat. I don't know about the other Myre blamish that has the pointed shell, or this type located anywhere else, as I stopped where I was and just hunted there.
