It can add an element of realism. By including the sound of a dragon's stomach growl, it makes the dragon seem more like a living, breathing creature with basic biological functions. This helps the readers to better imagine the dragon in its environment.
Another possibility is that the growling is a form of communication. In some fanfiction universes, dragons might use stomach growls to signal to other dragons or creatures around them. It could be a warning sign, like saying 'I'm hungry and might hunt soon', or it could be a call for help if the dragon is in distress and unable to find food.

Perhaps in the fanfiction, the Gingerbread Man is on a quest to find a way to become a real, living being. Lord Farquaad hears of this and decides he can use the Gingerbread Man's desperation to his advantage. He offers to help the Gingerbread Man in exchange for servitude. But the Gingerbread Man is no fool and manages to turn the tables on Farquaad, teaching him a lesson about greed and power.
Their interaction would likely be full of tension. Lord Farquaad is used to getting his way and the Gingerbread Man is a spunky character. Farquaad would probably be condescending towards the Gingerbread Man, seeing him as a mere treat. The Gingerbread Man, on the other hand, would not take kindly to Farquaad's attitude and would be sassy in his responses.
One idea could be that Lord Farquaad somehow returns from the dead but has lost his memory. Shrek, instead of seeing him as an enemy right away, decides to help him regain his memory. Along the way, they discover things about each other that they never knew before.
