Chapter 612

Chapter 612 is called "Brought by the Shark They Saved".

Cover
A Color Spread of the Straw Hats fighting and trying to escape brightly colored sharks while trying not to fall off the edge of waterfall.

Quick Summary
In a brief flashback, three mermaids struggle to find out what is inside the Straw Hat's barrel, unaware it contains Caribou. They manage to open just enough of the barrel for Caribou to escape. The mermaids try to flee to the water, but it's no use. Caribou is able to capture them with the powers of the Numa Numa no Mi.

The Straw Hats arrive at Ryugu Palace, where King Neptune is scolded for leaving the palace unguarded. Luffy sneaks off when he smells food. He comes to a large iron door that he mistakes for the banquet hall. Inside, instead, he accidentally meets the Mermaid Princess, Shirahoshi.
