Madagascar is purely fictional. The story and characters were invented by the creators to provide an enjoyable and imaginative adventure for the audience. There's no real-life basis for it.
I don't know who the author of the 'julian novel' is. There could be many people named Julian who could potentially be the author, or it could be a pen name.
I'm not sure specifically what a 'julian novel' is as the term is rather general. It could be a novel written by someone named Julian, or it could be a novel with 'Julian' as a main character. Without more context, it's hard to say.
I don't have specific information about who Julian is in '600 lb life' as there are many individuals on the show. He could be one of the participants who is on a journey to lose a significant amount of weight and improve his overall health.
Julian can be found in the Flash comics. He adds an interesting dynamic to the overall narrative. His presence often brings new conflicts and developments.
One idea could be exploring the backstories of the circus animals more in - depth. Maybe how they came together and formed their little circus family before meeting the Madagascar gang.
Well, a fanfiction about Joey in love in 'Penguins of Madagascar' could be really interesting. Maybe Joey falls in love with a new character introduced in the story, like a female penguin from a different colony. They could meet during an adventure, and Joey is instantly smitten. He might then try to impress her with his unique skills, like his ability to find the best fish in the ocean.
There could be many fanfictions about Baby Alex from Madagascar. It might focus on his early days in the zoo, his interactions with other animals there. For example, it could describe how he played with the other young animals, or how he first discovered his love for dancing.
