The Sling shot is a gun that is obtained in the first sea.
It is dropped by the boss Ussop in on the island syrup village ( Changed to maple village in the Ani-copyright update)
Note: It is a 5 percent drop.
Sling Shot v2 ( Must have v1)
You have to be in third sea and head to Bon Archipelago.
Kill Ussop at Bon Archipelago not at maple village.
It is 1% drop.
This is my first time editing a wiki so I hope it is good
