One idea could be that Timmy and Chloe discover a magical lemon grove that has the power to grant wishes in a different way than their fairies. They have to work together to protect the grove from an evil lemon - stealing villain. Another could be a story where they both get zapped into a lemon - themed alternate dimension and have to find their way back home while facing various citrus - based challenges.
Cosmo and Wanda would be great characters to include. They are Timmy's fairy godparents and can add a lot of magical chaos and humor to the story. Also, Jorgen Von Strangle could be included as he often pops up to enforce fairy rules. His no - nonsense attitude would contrast well with Timmy and Chloe's more light - hearted natures.
The story of Timmy Turner mainly revolves around a young boy with two rather mean babysitters. Timmy is granted fairy godparents, Cosmo and Wanda. He uses his wishes to deal with the typical problems of a kid, like getting out of trouble at school, dealing with bullies, and trying to get the attention of his crush. For example, he might wish for cool gadgets to show off or to become popular for a day. However, his wishes often go awry in comical ways, leading to a series of adventures and misadventures as he tries to fix the messes he creates with his wishes.
The key elements include Timmy Turner himself, a regular boy with normal kid problems. Then there are his fairy godparents, Cosmo and Wanda, who are crucial as they grant his wishes. Another key element is the wishes Timmy makes, which often lead to chaos. Also, the antagonists in the story, like the villains who try to get hold of the fairy godparents' magic, are important.
One interesting 'baby timmy turner fanfic' could be about baby Timmy's first encounter with his fairy godparents. Maybe he discovers them in a really cute and unexpected way, like they pop out of his diaper pail. It could be full of innocent and humorous moments as he tries to communicate with them with his baby babbles.
One common theme is redemption. Many fanfics explore Vicky's character and give her a chance to redeem herself in Timmy's eyes. For example, she might start to show kindness towards him after some event.
One popular 'Timmy Turner x Vicky fanfic' could be 'The Unlikely Bond'. It explores an interesting dynamic between them where they start to understand each other in a different way than in the original show.
A possible plot could be that Timmy's fairies accidentally send him to Gary's world. Gary is intrigued by Timmy's presence and the strange things that happen around him due to his fairy magic. They start to explore Gary's world together, and along the way, they face challenges like dealing with jealous classmates of Gary who don't like Timmy getting all the attention. In the end, they become good friends and Timmy manages to find his way back home with the help of Gary's intelligence.
The main characters are obviously Timmy Turner and Gary. Timmy Turner is a young boy with fairy godparents who often gets into wacky adventures in his hometown. Gary, depending on which 'Gary' it is (assuming it's from a well - known series), is likely to have his own set of characteristics. For example, if it's Gary from SpongeBob, he's a nerdy and hard - working character. Their interaction forms the core of the fanfic.
I'm not sure if there is an existing fanfiction specifically about that. There are a vast number of fanfictions out there, but this particular combination might be quite rare. You could try searching on popular fanfiction websites to see if anyone has written such a story.
