One Piece Chapter 28, page 16: The Crescent Moon

Nami slips down the oil-slicked slope and grabs Zoro's leg to save herself, dragging him down with her. Zoro screams, "AH!? WAAH!! LET GO! IDIOT!" while Nami apologizes, "OOPS! SORRY!" They crash to the bottom of the slope. Nami quickly uses Zoro as a stepping stone to climb back up, saying, "I GOT UP... THANKS!" Zoro slides back down, yelling, "WAAH!" Nami runs off toward the north, shouting, "SORRY! BUT MY TREASURE IS IN DANGER!" leaving Zoro struggling helplessly at the bottom of the oily slope.
