Kuro's grandfather was called "Black Lightning" by his friends because, long ago, he beat a dragon in a race. One of those friends, an old dog called Grampy, predicts that the dragon will soon return. Hearing this, Kuro decides to take up the challenge!

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?
It's for the snacks, right?
هذا من أجل الوجبات الخفيفة، أليس كذلك؟
Aber du willst doch
Süßigkeiten essen!
Lo hacemos por la comida.
C’est pour te remplir le bide.
Ma è per gli snack, ricordi?
Mas é pelo lanche, certo?
Но это же ради вкусняшек.
