I am somewhat skeptical of Goblin Drink being the pop item for Goblin Wolfman. Some of these reasons have been discussed but my primary reason is that it doesn't seem to fit with the other NM's that are forced popped that came in the June-August 2005 update.
A list of the Pop items used to pop NM's from this update.
Found (from ???):
Shield Bug
Dropped:
Air Tank
Clustered tar
Fomor Codex
Fresh Blood
Crafted:
Slice of Carp
Items:
San d'Orian carrot
Distilled water
Sleepshroom
Danceshroom
Woozyshroom
Honey
Pamamas
Crafted (requiring significant skill):
Antlion Trap
Shrimp Lantern
Adamantoise Soup
Premium Bag
For the regular NM's it's important to not that either the pop item is unique to this CoP update, or its a simple item that is easy to obtain -- including the slice of carp.
For the NM's that require specially crafted pop items, they require significant crafting skills and some effort is required to obtain the ingredients. When these items are used, they generate a special message signifying that the NM has popped. The following are taken out of the dialogue files for their corresponding zone. The regular NM's do not have this kind of dialogue.

There is no dialogue for Goblin Wolfman which follows this pattern. The dialogue is in line with a simple forced pop. We should expect that the item is a simple and mundane item which simply hasn't been considered yet.
It has been mentioned that time parameters may or may not be significant. Other forced pop NM's which are time sensitive indicate that they are time sensitive by some means or another. It is possible that the NM is time sensitive and the scrawled writing is always visible.
The fact he is called Goblin Wolfman may suggest he may follow the pattern of a werewolf. The other Goblins, Moblins, and Bugbears in the zone have titles that follow this "man" tradition but don't seem to indicate their job. The .dat file for the mobs in the zone do not indicate he has a pet so we can be sure he isn't a BST, DRG, or SMN (Pre-ToAU so definately not PUP). Perhaps everyone should make an effort to retry items during a full moon to ensure that this possibility is eliminated or confirmed.
Lately I have been working with ideas which might go with the "Scrawled Writing" or "Me Thirsty" clues. Why is he thirsty? Is it because he can't drink? Is it because he has no access to drink? Is it because he ate salty food? What might help him drink? Maybe he wants to be thirsty. Perhaps its a clue he will come out when he is given a reason to be thirsty. Perhaps giving him something to make him thirsty will make him angry enough to show up. Whatever it is I believe it needs to be a simple item that anyone has reasonable access too. Perhaps he wants a bretzel (I haven't tried that one yet but is bought cheaply from NPCs in 2nd+ place Bastok).
EDIT1: I actually intended for this to be placed in the Parade Gorget: Revisited thread. I was tired and clicked new topic instead of post reply.
