"Shinjitsu no Hata Jirushi" wa Tsune ni Tadashii

Synopsis

Inspired after reading an encyclopedia about the Stone Age, Nobita hatches an ambitious plan: travel to prehistoric times and impress primitive humans by introducing matches, flashlights, and radios—technologies they'd perceive as magical, elevating him to king-like status. Solo boarding the time machine, Nobita journeys back 50,000 years. However, a massive bison chases him into a river, causing him to lose consciousness. When he awakens, Nobita finds himself rescued by a Stone Age family whose youngest member, Sneeru, resembles Suneo. As Nobita struggles to adapt to prehistoric life, complications arise from cultural misunderstandings and technological barriers.
