A M'speak amulet (unstrung) is the unstrung version of the M'speak amulet used in the Monkey Madness I quest, as well as the Freeing King Awowogei subquest of Recipe for Disaster. Progress into Monkey Madness is required to make it. It is used to communicate to monkeys all around RuneScape.
To make one, the player must take Monkey dentures, an M'amulet mould and a Gold bar to Zooknock, who will give the player an Enchanted bar (and the mould back). The bar must then be used on one of the wall of flames underneath the Temple of Marimbo with the M'amulet mould in the player's inventory. This will create the unstrung M'speak amulet, earning the player 200 Crafting XP, and then must be used on a Ball of wool before it can be worn.
If the M'speak amulet is lost, it cannot be reobtained by any means other than repeating the above steps.
Since Zooknock returns the M'amulet mould to the player when the bar is created, only one M'amulet mould is required to create 2 or more Enchanted bars.
