Maybe the author or the original creator has restricted it. Some creators don't want others to write fanfiction based on their work to avoid misinterpretations or copyright issues.

I think Naruto would be really interesting. He's got his energetic and determined personality. In a fanfiction with Fairy Tail elements, he could learn all sorts of new magic and use his unique charm to make friends in the Fairy Tail world. His ability to never give up would be a great contrast to some of the more laid - back Fairy Tail characters.

A 'tails the werefox and cosmo fanfiction' could have a lot of different plotlines. One possibility is that it delves into the backstories of both characters in relation to each other. Maybe Tails became a werefox because of some event that also has a connection to Cosmo's past. It could also be a story about how they learn to work together better. Cosmo, with her plant - like nature, and Tails with his werefox powers, could combine their skills to solve problems. There might be elements of mystery, like trying to figure out the origin of Tails' werefox transformation and how it relates to the overall Sonic lore.
A great plot could involve the Nine - Tailed Fox being related to a powerful Fairy Tail spirit. So, when Naruto enters the Fairy Tail world, he has to figure out how to control this new connection. Also, what if the Sharingan was actually a form of lost Fairy Tail magic? A young Fairy Tail wizard could discover this and try to learn more about it from the Naruto characters. This would create a really interesting dynamic as they try to understand each other's powers and cultures.
It depends on the specific 'ya novel' about summer camp. Some may incorporate elements of fairy tales and make them real within their fictional world, while others might be more grounded in reality and not include such elements at all.

Well, given the title 'tails the fox tails is a baby fanfiction', it might be a creative work where the author has envisioned Tails the Fox in a baby - like state. Maybe it's about his early adventures or his relationships when he was very young in the context of a fan - created story. However, it could also be a very unique or abstract take on the character that doesn't follow the typical ideas we have about Tails.
