Well, you could write a Camp Buddy fanfiction about a character getting lost in the woods near the camp. The other campers then have to form search parties and face various challenges in the forest while looking for their friend. Another option is to write about a new camper who arrives late and has to adjust to the already - established groups and friendships at camp. It could be full of humorous misunderstandings and heartwarming moments as the new camper tries to find their place at Camp Buddy.
One idea could be that the characters' personalities shift slightly to match their new genders. For example, if a normally bold male character becomes female, she might be bold in a more feminine way, like using her charm and intelligence to get things done. Another plot idea could be exploring how the relationships between the characters change. Maybe a friendship that was more of a 'bro - like' bond turns into a deeper emotional connection with the genderbend. Also, the characters could face new challenges based on their new genders in the camp setting, such as different expectations from the camp leaders or other campers.
One idea could be Max trying to pull off a big prank on David during a camp event in the fanfiction. He might enlist the help of the other campers.
One idea could be a story where the campers discover a hidden underground cave system in the park that has prehistoric creatures not yet known to the outside world. They have to figure out how to survive among these new threats while also trying to find a way back to the camp.
One idea could be that Daniel tries to convert the whole Camp Camp David into his own religious vision, but the campers resist in humorous ways. For example, they play pranks on him during his sermons.
One idea could be a crossover where the characters from RWBY and Camp Camp have to team up for a special mission in a strange new world. They could combine their unique skills, like Ruby's scythe - wielding with Max's cunning plans.
One idea could be to cross Camp Lazlo with a magical world like Harry Potter. Lazlo and his friends could accidentally stumble into Hogwarts and have to navigate the wizarding world while still maintaining their goofy camp ways. For example, they might try to use their camping skills in the Forbidden Forest and end up causing chaos among the magical creatures there.
Maybe a story where the demigods have to face a new type of monster that is immune to their usual weapons and they have to find a creative way to defeat it. For example, they might have to use the environment in a way they never have before, like using the magic of the forest around Camp Half - Blood to their advantage. This would involve a lot of exploration and discovery within the camp's boundaries and its surrounding areas.
The girl could be a journalist or a writer who wants to do an undercover story on what goes on in a boy camp. So she sneaks in. While there, she experiences the camaraderie among the boys, the tough training, and the unique traditions. She also has to deal with her growing feelings for one of the boys she befriends, which complicates her mission.
A really cool plot could involve a prophecy that predicts the joining of the two camps. This could lead to some initial mistrust and rivalry among the demigods, but as they face common enemies and challenges, they start to bond and learn from each other. For example, the Camp Jupiter demigods could teach the Camp Half - Blood ones about Roman battle strategies, while the Camp Half - Blood demigods could show their counterparts some of their more unorthodox Greek magic.
One idea could be a quest that requires demigods from both camps to work together. Maybe they have to retrieve a powerful artifact that's being guarded by an ancient monster. The demigods from Camp Half - Blood could use their unique skills like Percy's water - based powers, and those from Camp Jupiter could contribute their Roman - style combat and discipline.
