It was pointed out that Chopper was imitating Nami when they ran towards Iceberg room.
Now I discover, a few late perhaps, that Chopper is dressed and posing like Nico Robin in the color page with all the mugiwara crew more Franky and CP9.
I suppose that is his way to try to be a pirate. And of course is a funny lil joke inside the history.
Any one has discovered any other imitation??
