One great 'Land Before Time' fanfiction about Littlefoot and Cera could be where they go on an adventure to find a special healing herb for an injured friend. They face many challenges like crossing a wide river and avoiding a group of mean dinosaurs. Along the way, they learn to trust each other more and their friendship grows stronger.
Littlefoot is the central character, but for some interesting twists, including some of the villains or less - friendly dinosaurs can be good. For instance, Sharptooth could be in the fanfiction not just as a mindless threat but with some kind of backstory that makes him more complex. Also, the old Threehorn leader who was a bit grumpy could add some conflict and humor to the story. And don't forget about the wise old dinosaurs in the Great Valley who can offer guidance to Littlefoot and his friends.
Littlefoot is always a great choice. He's the main character, and his growth and leadership throughout the story can be further explored. You can write about his internal struggles as he tries to keep his friends safe.
Littlefoot would be a great character to pair with Ducky. They have a strong friendship in the original series, and their different personalities can create interesting interactions. Spike could also be a good pairing. His quiet nature contrasts with Ducky's more talkative and curious self.
In a Land Before Time dragon fanfiction, the dragon could be a protector of the Great Valley. It guards against unknown threats from outside. The dragon's presence would change the way the characters interact with their environment and each other. For example, the other dinosaurs might initially be afraid of it, but then learn to trust it.
The 'Land Before Time' is about a group of young dinosaurs. Littlefoot, the main character, goes on a journey to find the Great Valley. Along the way, he meets friends like Cera, Ducky, Petrie and Spike. They face many challenges such as avoiding predators and crossing dangerous terrains. Their friendship grows stronger as they help each other through these difficulties and eventually reach the safe haven of the Great Valley.
The 'Land Before Time Novel' is mainly about the adventures of young dinosaurs in a prehistoric land. It shows their struggles for survival, like finding food and water, and also their relationships with each other.
One idea could be to write a fanfiction about what happened to the characters after the events of the documentary. For example, you could explore how Littlefoot and his friends continue to grow and face new challenges in their prehistoric world.
I'm not sure specifically which story Saro tells in 'Land Before Time' as there could be various tales within that world. Maybe it's a story about the adventures of the dinosaur characters, or it could be a legend passed down among their kind about how the land came to be as it is.
