Originally published in 1966 as a manga tie-in to an ongoing anime, this spin-off catered to a younger audience. Follow the adventures of Leo, a little lion cub, as he strives to protect his jungle pals from an aggressive red rhinoceros. Witness Leo's fierce boxing match against a rogue lion named Bubu, and his valiant efforts to avenge Lubar, an elderly leopard. Additionally, discover the fate of Laiya's brother, who, along with their entire family, fell victim to a hydra-snake. These riveting chapters of the Shogakukan Sunday Comics were once again made available to readers in 1994, as part of the Complete Manga Works edition of Bouken Ruby (冒険ルビ).
