There's one collectable that no one seems to have been able to Identify... it's between "Lump of Charcoal" and "Medicine Pouch". Anyone know?

The missing one (items above & below for reference):

Jack O Lantern
Kabuki Mask
Lump of Charcoal
UNDISCOVERED <------ MISSING THIS ONE!!!! D:
Medicine Pouch
Nessie Tooth
Old Candle

There seems to be 8 Halloween items, 4 standard low-point treasure items, and 6 species-related for each of the 5 species... which totals 42. With the unknown item, the full list totals 43....

So, it's not species related, Halloween-related, or one of the 4 main low-point treasures... thoughts? *cue jeopardy music*

Also, I will post 3 responses to this.

1. Full tome list with associated species (items in alpha order).
2. Tome list broken down by species/category.
3. Treasure codes from a specific treasure finder which shall remain unnamed so as not to "advertise". (Shows up in local as "Your Meeroo dug up a Treasure [zex]!"

Please respond with info that you guys know can fill in some blanks! :)
