Well, in this fanfiction where Alvin gets sick, it could start with Alvin waking up one day feeling really unwell. He has a high fever and can't even sing his favorite tunes. Simon, being the smart one, tries to diagnose what's wrong with him using his vast knowledge. Theodore, on the other hand, is just worried sick and keeps bringing Alvin his favorite snacks, thinking that will make him better. As the story progresses, they might face some challenges like not being able to find the right medicine in time or having to deal with Alvin's crankiness due to his illness.
Maybe Alvin gets hurt in a minor accident like falling off a tree while looking for a lost item. His brothers, Simon and Theodore, rush to his aid. Simon tries to use his intelligence to treat Alvin's injury, while Theodore is just there to comfort him. As Alvin recovers, he realizes how much he depends on his brothers and vows to be more careful in the future. It could be a simple story about brotherly love and the importance of looking out for each other.
In Alvin x Simon fanfiction, they might go on an adventure together. For example, they could get lost in the forest while trying to find a special type of nut for a recipe. During their time lost, they rely on each other's skills. Alvin uses his quick thinking and physical abilities to get them out of some tricky situations, like crossing a small stream. Simon, on the other hand, uses his knowledge of the forest's flora and fauna to find food and shelter. Through this adventure, their bond grows stronger.
Perhaps Alvin's sickness could lead to a big concert being postponed. This would create a lot of chaos among their fans and management. But the chipmunks would be more focused on getting Alvin well. They might call in a famous doctor from the animal world who has a special way of treating sick chipmunks. This could introduce new and interesting characters into the fanfiction.
In a fanfic where Alvin is in prison in the 'Alvin and the Chipmunks' universe, it could be a really interesting take on his character. He might face challenges from other inmates who don't like his upbeat and sometimes mischievous nature. However, Alvin could also bring some positive change to the prison, like starting a music group among the inmates to pass the time and boost morale.
One possible plot for such a fanfic could be that Alvin gets separated from the group during a concert tour. He might find himself in a small town and has to rely on his wits to get by. He could meet new friends who initially don't believe he's a famous chipmunk but eventually help him reunite with his brothers.
One common theme is friendship. Since they are part of the same group, many fanfics explore how their friendship grows and changes over time. It could be about them becoming closer friends through shared experiences like going on tour or dealing with a difficult performance.
One interesting storyline could be Alvin and Jeanette going on a musical adventure together. They might discover a new genre of music and collaborate to create a unique sound. This could involve them exploring different parts of the city to find inspiration, like old music stores or street performers.
They could compete in a school - like setting. Imagine they are in a chipmunk academy and there's a big academic competition. Alvin is more street - smart and Simon is book - smart. They initially see each other as rivals in this competition. But as the story progresses, they realize that by combining their different types of intelligence, they can outperform all the other chipmunks.
One idea could be a crossover with the Smurfs. Alvin and the Chipmunks could accidentally wander into the Smurf village while on an adventure in the forest. They might initially be seen as strange little creatures by the Smurfs, but then they team up to save the village from Gargamel who has a new plan that involves using the Chipmunks' musical talents to lure the Smurfs.
Another way for them to recover is with the help of proper nutrition. Theodore loves to eat, so he could be given some healthy foods like fruits and nuts that are rich in vitamins. Simon might need some special herbal teas that boost his immune system. And Alvin could have some warm soups that soothe his throat if he has a cold. Also, the love and care from their friends, both human and chipmunk, can play a big role in their recovery. Their friends could keep them company, read stories to them, which would make them feel better emotionally and physically.
