A comedy about a group of kids forming a school baseball team, with the leader being very stubborn and argumentative.

This was the first episode of Mushi Pro Land, a unique series of 60-minute animated programs. It was also Japan's first 60-minute animated TV program. However, the series never materialized and only this episode was actually aired. The story follows Stevenson's "Treasure Island," featuring characters in the form of animals. For example, the pirate Silver is illustrated as a wolf, where the main character Jim is changed into a rabbit. This has, therefore, nothing to do with the "New Treasure Island," Tezuka's masterpiece Manga.

In the summer of 2000 in Hollywood, Spielberg's Dreamworks Film Corp. made the film "Chicken Run" with Nick Park, the great master of clay-figure animation, and it became a big hit. A chicken was the main character, and the story unfolded like the masterpiece "The Great Escape." Thirty-five years ago, Mushi Production created an animated work in which a chicken was the main character and a rebellion between the rulers and the ruled eventually escalated into a great war. Despite the scale of the story, the film ran for only three minutes. The ability to depict the endless repetition of war in human history in just three minutes is a unique feature of short animation, relying on exaggeration and great imagination.
