Sticking with the Dual Squelcher, and improvising the start, where I move around my squidmates. I think that Inkbrush is going to be a problem for me, but it seems the Sprinkler is more my nemesis.
I really do try to make use of my weapon's range, when I have it, but it seems like I can't accomplish much without closing the range, which inevitably gets me splatted. I honestly don't care for constant jumpers, though.
I don't think I'm going to do much in this battle, same as the last, but a bit of fortune gets me three splats in quick succession, and boosts my mood. Getting splatted by another Sprinkler is just unfortunate after that.
It's a closer battle than I would have predicted after the start, but close only counts in horsehoes and hand grenades.
