One Piece S04E56 - Robin Struggles! Sogeking's Clever Scheme!!

After hiding under Robin's cloak for a few episodes, Sogeking finally shows himself. They stumble into the room with the CP9 and meet with Sanji and Franky. Sogeking produces a smokescreen. The four head into another car, detach it, and escape. It's not long before Blueno pulls their car back, though. Franky knocks down the wall so they can escape but ends up on the enemy car. Blueno opens a door then back in the Straw Hat car.
