The sextuplets' ability to derail any narrative is the joke, and a quest for a wish-granting fruit is the perfect setup for that chaos to unfold across a whole movie. Their comedic timing as a unit, built across six seasons, means every brother's failure compounds the last one in ways a standalone would never land. What saves this from being just another gag-structure adventure is that these six have already earned the right to waste your time being stupid together.
The six Matsuno brothers stumble onto rumors of a mythical fruit hidden somewhere in the world, one that supposedly fulfills any wish for whoever eats it. Naturally, they decide to hunt it down, because why work when you can chase an impossible legend instead. What follows is a chaotic expedition packed with the kind of absurd mishaps and slapstick humor that defines the series. Along the way they encounter the Hipipo tribe, whose culture and quirks add another layer of weirdness to an already ridiculous journey. The movie leans hard into adventure comedy, mixing genuine excitement with moments that completely undercut the stakes through sheer stupidity and bad timing. The brothers bicker constantly, split up for contrived reasons, and somehow manage to make a treasure hunt feel like a vacation where nothing goes according to plan. It's lighthearted and energetic, never taking itself seriously even when the plot genuinely picks up momentum.
