Part 1 (2 chapters)
Another two story manga. The first story is about a girl named Ruby who discovers a mask that gives her powers that was granted by an alien visiting earth. This version of the story is the one originally serialized in Shougaku Ninensei (for second grade students) and Shougaku Sannensei (for third grade students). The other version is included in the Osamu Tezuka Complete Manga Works edition of Marvelous Melmo.

Part 2 (4 chapters)
The second half is remarkable in that it is Jungle Taitei ジャングル大帝, simplified and re-written for 3rd grade students. This was a tie-in manga for the then ongoing anime in 1966. As a little lion cub in the jungle, Leo must find a way to stop an aggressive red rhinoceros from hurting his jungle friends. A boxing match between Leo and a rogue lion, Bubu breaks out. Leo saves a brave hero as he gets revenge on Lubar, an elderly leopard. Finally, Laman, Laiya's long-lost brother tells a story about how a hydra-snake was able to devour their entire family.
