Apparently the episodes about what they got up to after that story aren't filler?
Not sure what the point of skipping filler is if there's just going to be canon filler episodes anyway.
I really do not actually give a shit what Coby is currently up to, One Piece.
Coby is important. So are those 2 Coby episodes. For reasons. You'll understand eventually. That's how it works with One Piece.
I never did post my breakdown of how to watch One Piece in manageable sittings, did I? Might as well do it now. Here's how to catch up to current One Piece as painlessly as possible. Note that this assumes not skipping any filler, but it does have all the filler marked so you can skip over it if you want to. Episodes are generally grouped thematically and try to leave off on interesting climaxes or cliffhangers, which I discovered in the process of originally organizing this seems to happen at a surprisingly rhythmic pace.
Lines marked in red contain at least one filler episode (filler episodes in that group labeled at the end). Lines marked (FILLER) are comprised of
nothing but filler episodes.
Also nothing is spoiler-marked, since it's all pre-current Toonami.

With skipping filler, that's about 2 months to catch up all the way through Robin's backstory by watching 1-2 hours per day. Mixing and matching or tossing in a few binges here and there can catch you up even faster. Of course, this was originally designed as a weekly schedule, so that would have you catching up in about a year and a half, as opposed to the 5 and a half years the weekly broadcast pace would take.
