The Adventurers - Gamba and Co. - v1.0
"The Adventures - Gamba and Co. - was a juvenile animal story in early 70s and the best favorite in my childhood. It was more than 30 years ago. You can still buy the book. Super recommended.
The original story has a subtitle "Gamba and 15 Colleagues" but the animation reduced the number of rats to avoid something messy so that the visual version is known as "Gamba and 7 Colleagues". To take photos of rats, I have double checked who are 15 or 7, and found that Shioji may be one of the 15 or 7. Is it correct? I don't know..
Anyway, the must-read story for kids. The proceeding "Glick's Adventure" and the later released "Gamba and the Otter" are also recommended.
