“A Promise Between Men! Luffy and the Whale Vow to Meet Again!”

The Straw Hats are on the way to the Grand Line and the path gets distracted by a giant whale.

Yes, a giant whale.

Laboon is his name and he wound up swallowing the ship of the Straw Hats. They give the whale a backstory and a reason why he was pounding his head against the Red Line. The show introduced Crocus as the man who watched and tried to help Laboon.

We also get two more assassins inside the whale. Miss Wednesday and Mr. Nine are the two assassins from a group and I do not think we ever found out why they were inside Laboon.

I do love the way that Luffy painted the straw hat on Laboon to symbolize that he was the part of the Straw Hats and keep him from pounding his head into the Red Line.

This was a fun side adventure with Laboon. The whale actually turned out to be a pretty cool character for the show.
