In this story, there is a mystery about a green gas that people can see if they fart.The story begins with just a normal boy named Julius, who is not that great at typical academic school subjects. He lives in a family where his father has just gotten divorced and this makes him upset. But as the story develops, he finds himself solving a mystery with a strange person who acts like a zombie. Towards the end he tries everything to enter his theories of the case.

Julius Caeser Brown has a big problem. He has Space Pop cereal that he can't resist eating. But he is not the problem; the Space Pops are. The Space Pops give people "green gas"! Julius doesn't know how the Space Pops make people have green gas. Can Julius find out why the Space Pops are giving people gas before it's too late? 

Julius Caesar Brown and the Green Gas Mystery is a… ppppffffffffffffffffffffttt! Oops, sorry, I should be careful next time. As I was saying, it is a humorous and fictional story by Ace Hanson. It is about a mysterious green gas that for some unknown reason is making people gassy! About every let’s say, seven minutes someone poofs green gas. The story takes place in a small town and in a middle school. The characters, are well, duh; of course Julius Caesar Brown is one but I didn’t tell you about Miss Crabtree.
