One Piece S04E61 - The Means of Escaping is Opened! Fly through the Sky, Rocketman!

While Robin and Franky are brought before Spandam, Luffy blasts his way through another wave of marines. In order to get past the gate, Zoro orders that they just keep going. Yokozuna the frog bends down the outside gates and they fly over the gate inside. Back on the ground, Paulie is stabbed by someone from "The Law's Watch Dogs", the Houbantai. The Rocket Man flies over the gate and the point of the train smashes into Oimo's back, knocking him out cold.
