Ah okay~ The first two thangs are easy to find. They actually are on the lines B and C, which are on either side of line A. Which is your starting point.
I caught them all and got banned. Probably should not have sniped the continent specific ones.... Oh well.
*buzzes happily* Well, I finished the Octo Expansion last night~ Talk about a trip~ Now I ish able to switch between a Octoling and Inkling whenever I wish. And don't worry about stats, gear, and weapons. Your Octoling gets all that carried over from your inkling. And your Octoling's tentacle hair will have different colors like your lnkling does once out of storymode. So yay~
