A'mumbo jumbo novel' might be a made - up or very niche concept. It could potentially be a novel that has a lot of jumbled - up ideas, like a stream - of - consciousness style where the narrative jumps around a lot and is difficult to follow at first glance. Maybe it's a new genre someone is trying to create that combines elements of mystery and chaos in the storytelling.
The 'jumbo josh sad origin story' remains a mystery without further details. However, generally speaking, an origin story often involves how a character came to be, their early life experiences, and what led them to be the way they are. So for Jumbo Josh, perhaps in his past he was betrayed by a friend. This betrayal could have been the start of his sadness. He might have trusted this friend completely, and when the friend turned on him, it shattered his world. This could have led to a series of events that made his life take a sad turn.
No. Given that the very name'mumbo jumbo' gives the impression of something rather odd and unstructured, it's not a type of novel that I've had the opportunity to read. It might be a work that is only known within a very small circle of readers or writers who are into more avant - garde or experimental literature.
Jumbo the little elephant is a very cute character. In the story, Jumbo often has various adventures in the jungle. He might be making friends with other animals or exploring new places.
I'm not very familiar with this specific 'antique book jumbo the elephant and other stories'. It might be a rather unique or less - known collection. Maybe it contains stories about Jumbo the elephant, perhaps his adventures or how he interacted with other characters in an antique - like setting.
Since I don't know the details of the 'jumbo josh sad origin story', I can only speculate. Maybe Jumbo Josh was an outcast from the beginning. He might have been different from others in his appearance or abilities, and this led to him being shunned by society. This constant rejection and isolation could be the source of his sadness in his origin story.
