* Based on Robert Louis Stevenson's Treasure Island, but featuring the characters in the form of animals instead; for example, the pirate Silver is illustrated as a wolf, whereas the main character Jim is changed into a rabbit.

Note: This was supposed to be the first episode of Mushi Pro Land, a unique series of 60-minute animated programmes; it was also Japan's first 60-minute animated TV programme. However, the series never materialised and only this episode was actually ever aired.
