While continuing to use the hot air balloon to search for the oil, it's decided that Ishigami Village needs to take up agriculture to prevent future food shortages, as well as to produce preserved food for their upcoming sea voyage.
And once we get the king of fuel that is oil,
،بمجرد أن نحصل على النفط ملك الوقود
Mit dem Erdöl, dem König der Treibstoffe,
kommen wir überall auf der Erde hin!
Con petróleo, el rey del combustible,
Con petróleo, el rey del combustible,
Dès qu’on aura le roi,
à savoir le pétrole,
e quando avremo ottenuto 
il re dei carburanti, il petrolio,
E quando conseguirmos petróleo, 
o rei do combustível,
и, как только добудем
лучшее топливо — нефть,
