Takeshi's backpack is filled with snacks. Tama, accompanied by Tora and Pochi, goes chasing after him and his classmates on their class outing. They cross railroad tracks and rivers, facing many dangers... Will Tama and the others ever find the snacks they seek?
everyone's backpacks were lighter, 
with empty lunchboxes and snack packs.
كانت حقائب الجميع أخفّ، تحتوي على علب
 .طعام ومغلّفات وجبات خفيفة
war alles aufgegessen worden,
also war das Gepäck leichter.
tutti avevano gli zaini più leggeri,
con portapranzi e pacchetti vuoti.
todas as mochilas ficaram leves
sem a comida e pacotes de lanches.
рюкзаки полегчали — остались только
пустые контейнеры и пакеты от еды.
