Chapter 346 is the third regular chapter of the week (3 out of 3 complete) brought to you by June and Ninja. As Owl suggested in the comment section there is a difference between whirlpool and waterspouts. The author seemed to be describing a waterspout so going to change it to waterspout.
Also f you have any spoiler questions please posted it here and in other post so I can answer it. People reading the chapters may not want to know what happens next 🙂
