A talking "heroic" but actually quite cowardly, lazy, treacherous, and funny pig that appears in some of the episodes and chapters about ancient Japan. The character is a product of Shin-chan's imagination, but carries on as though he is a popular character. His appearances are limited, due to the fact that his voice actor, Kaneto Shiozawa, died in 2000, and the character has not had a speaking part since. The "Buriburi" of his name is the Japanese onomatopeia for the sound that poop makes when it takes off anus, while the "zaemon" is a typical samurai name suffix. (Source: Wikipedia)
