The Uzumaki-Namikaze clan holiday to the Hidden Sand was meant to be a relaxing getaway. Naruto, ever the exuberant Hokage, imagined lazy days by the oasis, developing sandcastles with Boruto and Himawari, and perhaps even some high quality time with a less-stressed Hinata. Nevertheless, from the moment they stepped off the train, turmoil took place. Boruto, quickly tired with the "calm desert," started a prank war with the Sand Siblings 'youngsters, transforming the relaxing oasis into a field of battle of blowing up sand clones and dyed-orange cacti. Himawari, in her commonly innocent however deceptively powerful method, stumbled upon an unusual and exceptionally hot desert chili, causing a village-wide inferno of coughing and watery eyes. And Naruto? He handled to inadvertently challenge Gaara to a sand-surfing contest, the results of which were... less than dignified for the Hokage. What was meant as a household bonding experience swiftly spiraled into a testament to the Uzumaki's special brand of disruptive love, leaving everybody questioning if a holiday was genuinely worth the taking place jangle.
