Luffy is so focused on his own goals of the future that he hardly even thinks about past struggles or enemies. While we see that Luffy lives rent free in Buggy’s mind, Luffy doesn’t even think about Buggy, similar to that Mad Men meme. Luffy only cares about becoming king of the pirates and his humility means he doesn’t obsess over old victories.
Buggy does continue to have a very positive & optimist outlook on his adventures. After building a very rudimentary raft, he is proud & excited about his small progress, which is a noble attitude. Even his words “bad luck just makes me stronger; bring it on,” emphasize a determined attitude that grows & learns from adversity. This is further explored when Buggy is upset, almost angry, when the bird spits him out, even though the avian disgust is likely what saves the clown pirate’s life.
We see a number of animals in this episode, and although we saw the ones on Gaimon’s island before, it seems maybe their anthropic nature is related to the bird we see here wielding a knife. The ability to use tools is often seen in the animal kingdom, and if One Piece is indeed set in the post-apocalyptic remains of our own world, it would make sense that regular animals have continued to evolve and are better suited to use tools abandoned by the human race.
Jack in the box is back! What a cool guy. Now that he has accepted that his place in life is protecting the animals on this island with a gun, his entire demeanor seems calmer & more serene, demonstrating how much a shift in perspective can affect us. Perspective is also addressed when we hear Buggy & Gaimon sharing stories of young pirates they have encountered, with entirely opposite opinions, even though they are discussing the same pirate. Although Buggy & Gaimon have some shared culture & agree on a lot of things, their differed interactions with Luffy color their memory of him, resulting in divergent reputations for the Straw Hat captain.
Last note, we also see another hermit crab, this one falling off of the Straw Hat ship. Based on the last time we saw this creature used as a narrative metaphor, it does appear to be a bad omen for whatever is to come next.
