A king so devoted to napping and omelets that his entire kingdom revolves around his next meal. The comedy lives in pure silliness, where the stakes are always whether Ou-sama will successfully prank his counselors before hunger wins. This is a show built for people who need something warm and ridiculous, where a grown king throwing tantrums over egg size is exactly the kind of problem worth solving.

King Ou-sama is silly, greedy for food, lazy, and thoroughly lovable, and his days are one misadventure after another. He goes looking for elephant eggs because they make the largest omelets, and omelets are his favorite dish. He tucks toys away in the forest to play tricks on his three wise counselors, and he rides his bike around the castle. The TV series adapts a long-running Japanese children's book series by Teruo Teramura and Shizuko Wakayama that began in 1959 and grew to fifty volumes. Every episode pairs a story with a hiragana reading lesson. Episodes 7 to 12 repeat the stories from the first six with different lessons.
