Harmonica (Fallout 3)

Harmonicas are stashed sparsely throughout the Capital Wasteland and Fallout 3 add-ons. They are only useful as Rock-It Launcher ammunition. They are somewhat rare except for random placement in containers or on creature bodies. Feral Ghouls and Centaurs will occasionally have this item in their inventory.A few merchants and traders such as Moira Brown and Crazy Wolfgang on occasion will sell them. (at least 1-2)Sometimes swampfolk will carry them, such as (Bruisers, Creepers etc.)
