The Franky Family and Iceburg!

The people who attacked Zoro reveal themselves to be the feared "Franky Family", though they're no match for Zoro. Luffy-tachi have their gold exchanged for cash. After, they meet a man who resembles Usopp, Galley La's carpenter employment foreman, Kaku. Usopp's cut of the money is stolen by the Franky Family.
