Looking at the text on the "Edit this page" tab, I thought it best to just put this information here so that someone who knows what they are doing can make the proper changes.
I just did a treasure map -- level 41, solo, Lower La Noscea -- and had to fight 3 waves of puddings. The first two waves both dropped Pudding Flesh as loot from kills. The names of the mobs who dropped it are: (1) Territorial Marshmallow, and (2) Territorial Bavarois. The third wave consisted of Territorial Puddings and I'm guessing that there's a chance for these mobs to drop Pudding Flesh as well. I believe that the creature levels for this map were 41, 43 and 45, respectively. Two of each type of critter spawned for each wave.
