Characters

 * Pyonkichi (ピョン吉)
 * A frog who is crushed by Hiroshi, but his spirit lives on as a talking frog on his shirt, becoming a "Flat Surface Frog" (平面ガエル). Because said shirt is Hiroshi's only good shirt, he is always forced to travel around and interact with Hiroshi. They are equally obstinate and gluttonous and are always arguing like siblings. He is capable of jumping around and forcing Hiroshi to come along with him. He possesses incredible strength, and through his arms and teeth he is able to lift extremely heavy objects. Hiroshi's mother treats Pyonkichi as her own child. Pyonkichi is attracted to females of all species; including cats, frogs and humans. His title comes from his frequent acts of "gutsyness".

 * Hiroshi Kaizuka (貝塚 ひろし)
 * The middle schooler who fell on Pyonkichi. He is never seen without his sunglasses, which he wears perched on his head.

He frequently engages in duels with other boys including Gorilla-Imo. Hiroshi is recognised as the class comedian due to his mischievous acts, and consequently is scolded often by his teachers. His girlfriend is Kyoko, whom he stays with most of the time. Though he still does not miss an opportunity of seeing out other women, especially older ones. Pyonkichi and Hiroshi behave like siblings; encouraging, quarrelling and caring deeply for each other. Married to Kyoko in the Solmac advertisement series produced by the original animators.
