One Piece S04E59 - Luffy Charges In! Great Decisive Battle on the Judiciary Island!

Spandam is informed that an intruder has entered the area. Luffy confuses the Marines guarding the entrance gate by manipulating one of their own comrades to fight against them. The rest of Luffy's group come in after he already slingshot himself over the gates. Because they aren't all quite as limber as Luffy, they have to band together to get inside. Giant Gate Keepers Kaashii and Oimo come to fight the Franky Family.
