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.
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.
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.
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.
The Chipmunks were created by Ross Bagdasarian Sr. in the late 1950s. He had the idea of creating characters with high - pitched voices. He used a sped - up recording technique to give the Chipmunks their unique voices. Alvin was the mischievous leader, Simon was the smart one, and Theodore was the cute and chubby one. They first became popular through a song called 'The Chipmunk Song (Christmas Don't Be Late)', which was a huge hit.
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.
The character of Smart Alvin himself. He's a very unique character with his high intelligence. Fanfics can explore all the different ways his intelligence can be used, whether it's to solve mysteries or come up with cool inventions. It gives a lot of room for creativity.
It's about the adventures of Alvin and the Chipmunks. They are these really cute and mischievous chipmunks that get into all sorts of fun and sometimes tricky situations.
I'm not sure specifically as I haven't read that particular fanfic. But generally, in Alvin and the Chipmunks fanfics, it could be about the chipmunks having some unique adventures, maybe with a twist of lemon which might imply some sour or difficult situations they face.
