Bono-čan: Tatte mijó (E81)

"This story is about my father and me when I was a baby." Bonobono's father gave Baby Bono some fish and shellfish to eat, but he tried to put a rock in his mouth and eat a shellfish without cracking it. His father was worried he couldn't eat, but manages to feed him. Now, it's on to standing practice. (Crunchyroll)
