Zach and Fred are best friends. They always have fun no matter where they go. Fred can be a little stinky sometimes, and he always eats way too much, but he is the greatest friend a kid could have. When Zach is happy, Fred farts, sings, and wiggles. When Zach is shy, Fred farts for giggles. Fred is an invisible dinosaur that burps, farts, and sneezes. Zach is the boy he loves to pieces. Fred's real name is long, like his never-ending tail. He can only be seen by Zach, Emily, and Dale.
