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.
The plot could also be centered around Sid getting sick. Diego, who is usually tough and independent, is really worried about Sid. He goes to great lengths to find a cure, traveling to far - off places in the Ice Age landscape. This shows the depth of their friendship.
Perhaps in a fanfiction, Diego and Sid decide to teach some of the younger animals in the herd some important skills. Diego shows them how to hunt safely, while Sid teaches them about the importance of sharing and cooperation. Along the way, Diego and Sid have some friendly competitions between themselves, which adds some humor to the story.
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.
They might have a friendly competition. For example, they could see who can hunt the biggest prey in a day. This would not only show their skills but also add some fun and flirting to their relationship. It could also lead to them respecting each other more.
One possible plot could be that Diego and Shira go on a journey to find a new place for their pack to settle. Along the way, they face various challenges like crossing a dangerous river and avoiding a group of hunters. They have to rely on each other's skills, with Diego's strength and Shira's agility. Their relationship deepens as they overcome these obstacles, and they end up leading their pack to a beautiful and safe new territory.
In a fanfiction, their love might start with a misunderstanding. Diego mistakes Shira for an enemy at first sight. But as he gets closer to her, he realizes she's just a misunderstood creature. Shira, in turn, is initially wary of Diego. However, as they are both caught in a dangerous situation, like being trapped in a cave during an earthquake. They have to rely on each other to survive. This experience makes them see each other in a new light and their love begins to blossom.
Maybe the fanfiction could focus on how their relationship changes during the pregnancy. Diego becomes more tender and loving, and Shira becomes more dependent on him in some ways. They could also have some arguments about how to raise the cub. For instance, Diego might want to teach the cub to be a fierce hunter from the start, while Shira thinks it should first learn to be gentle and kind. These differences in opinion add some spice to the story while they are waiting for the new life to arrive.
There could be a story where Diego and Shira compete in a friendly competition to see who can hunt the most prey in a day. It would show their competitive sides and also how they respect each other's abilities.
One possibility could be that the story focuses on how Diego and Shira prepare for the arrival of their baby. They might face challenges like finding a safe place in the ice age world, gathering enough food, and protecting their future cub from other predators. Maybe they'll get help from their friends, like Manny and Sid.
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.
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.
