Gum Gum Punch (ガムガムパンチ, Gamu Gamu Panchi) is a manga by Osamu Tezuka that began serialization in 1967.
Plot
In this children's manga, Punch and his sister Pinko are approached by a strange man calling himself the God of Gum. Looking like a kind of eccentric scientist, he explains that the gum he has is special as it will allow the gum chewer to create whatever they want with the bubbles they blow. However, since Punch and Pinko are still young, they have not mastered the ability to blow bubbles.
Seeing as this might be a problem, and to prevent the children from potentially misusing the gum, the God of Gum assigns his disciple, Gum Gum, to stay with the children. Together, the three explore the many possible uses of the magical chewing gum and get into mischief.
