Izzy's mark

Izzy's mark is an item from the Rocking Out quest. It is one of the five marks needed for the quest, in order to make Young Ralph talk about Rabid Jack.

If dropped, talk to Cap'n Izzy No-Beard again to get another:
 * Player: I lost your mark.
 * Izzy: How could ye? There, and ye'd best keep yer eye on this one.
