I'm not saying tomorrow's One Piece is the best episode ever but it is the best one in this arc and memorable as hell.
The dub version of it is particularly good.
Indeed, it's
so funky
I also want to address the two filler losses the Straw Hats suffered. In the manga, they only lost once, and that was during the boat race. This was caused by Foxy using his Slow Slow Fruit powers, introducing the readers to his ability.
The filler losses were both complete bullshit, because Toei couldn't think of a decent way for the Straw Hats to lose. Instead we got "eating the ball is against the rules" and "Zoro kicks Hamburg and he lands in the right place".
It's also why I want to see a One Piece Kai years down the road (that and the pacing of later arcs).
