One possible fanfiction could be about Diego and Sid going on a special adventure together. Maybe they get separated from the herd and have to rely on each other's unique skills to survive. Diego's hunting abilities and Sid's knowledge of different plants and hiding spots could combine to make for an exciting story.
A simple plot could be that Diego and Sid find a mysterious object in the ice. They both have different ideas about what it is and what to do with it. Their bickering and attempts to figure it out could be really fun to write about.
Well, Manny's story in Ice Age 2 is most likely a cautionary one. He's seen the signs of the changing world around them, like the cracking ice and the strange weather. His story probably details how they need to stick together in the face of this impending disaster. He might talk about the new challenges they will face, such as finding food and shelter in a world that is being rapidly transformed by the melting ice. It's a story that serves to unify his group and give them a sense of purpose and direction during a very difficult time.
A fanfic could focus on the relationship between Diego and Shira. Maybe Diego wants to show Shira a special place he found in the Ice Age wilderness. It could be a beautiful hidden valley with warm springs. Along the way, they talk about their pasts, how they became the tough sabers they are now. And at the end of the journey, their bond grows even stronger.
A fanfiction idea could involve Diego and Shira's relationship. They might have an argument over how to protect their group. Shira could think Diego is being too overprotective, while Diego believes Shira is taking too many risks. But in the end, they realize they both have the same goal and make up, strengthening their bond.
In a fanfiction, Diego and Shira could be on a mission to save a group of baby animals that got separated from their families during a big ice storm. Along their journey, they share their past experiences with each other. Diego tells Shira about his time with Manny and the others, and Shira opens up about her own struggles. This sharing brings them closer together.
Manny is a woolly mammoth in Ice Age. His back story is quite sad as he lost his family. He was all alone in the world which made him initially a bit of a loner. But as the story progresses, he finds new friends and a new family of sorts among Sid, Diego and others.
Once upon a time in the Ice Age, Sid, the sloth, found himself in a rather strange situation. He was magically transformed into a woody animal. He had a tough, bark - like exterior but still had his goofy sloth personality. Sid, now looking like a walking tree stump, tried to blend in with the forest. But his clumsy movements gave him away. His friends Manny and Diego were both confused and amused when they saw him. They couldn't stop laughing at how Sid waddled around as this odd woody creature.
There are many fanfictions that explore Diego's love in the Ice Age. Some might depict him falling in love with another character within the Ice Age group, like Sid's sister if he had one. It could be a story full of adventure and new challenges as they face the harsh ice age environment together.
Survival is also a big theme. Given the Ice Age setting, fanfictions often depict Diego using his hunting skills to ensure the group's survival. He might face new threats like harsher winters or more powerful predators.
