What could be the plot of a 'Spongebob x Homer fanfic'?

Mr. Burns could potentially be the antagonist. He might see the combination of Spongebob and Homer as a threat to his power in Springfield. He could try to separate them and cause trouble for them. Maybe he wants to take over Bikini Bottom as well, seeing it as a new source of resources or power. He starts by spreading rumors about Spongebob and Homer in both their hometowns to turn the locals against them.

Perhaps the fanfic could center around a lemon - based competition in Bikini Bottom. Spongebob and Sandy team up to compete. Along the way, they face challenges that test their friendship and they learn more about each other's strengths. For example, Sandy's scientific knowledge combined with Spongebob's boundless enthusiasm helps them get through the tough tasks in the competition.

Well, it could be that a lemon from the surface world falls into Bikini Bottom. Spongebob, being his curious self, decides to investigate it. He finds that the lemon has a unique smell that attracts all the fish in the town. This causes chaos as everyone is crowding around the lemon. So, Spongebob, with the help of Sandy, tries to find a way to deal with this situation. Maybe they build a special container for the lemon to keep its smell contained.

Well, it could be about Spongebob and Patrick starting a lemonade business together. They might face challenges like finding the best lemons in Bikini Bottom. Maybe Mr. Krabs tries to take over their business because he sees its potential for profit. They then have to come up with creative ways to keep their lemonade stand independent and successful.

Well, it could be that Spongebob falls in love with a new character in Bikini Bottom. Maybe a mermaid who visits from afar. They meet when Spongebob is out jellyfishing and she gets caught in his net by accident.

One plot idea could be that Mermaid Man takes Spongebob on a special mission to save Bikini Bottom from a new and mysterious villain. Spongebob, being his eager self, follows Mermaid Man's every instruction and in the process, they form a deeper bond as friends. Another could be that Mermaid Man decides to train Spongebob to be a proper sidekick, leading to comical training sessions where Spongebob tries his best but often fails in a humorous way. Maybe there's also a plot where Mermaid Man loses his memory and Spongebob has to help him remember who he is and his heroic deeds, all while facing the challenges that come with Mermaid Man's altered state.

Friendship is a very common theme. Since Spongebob and Patrick are best friends in the original show, fanfics often explore different aspects of their friendship, like how they support each other or overcome differences.

Adventure is also often seen. Since Spongebob is always up for an adventure and Sandy is quite brave and intelligent, they make a great team for exploring new places in Bikini Bottom or even beyond. For example, they might discover a hidden underwater cave or an ancient artifact. This makes for exciting stories.

The plot could be that there's a strange event in Bikini Bottom that makes Squidward and Spongebob have to rely on each other more. During this time, Squidward discovers that Spongebob's simple - mindedness is actually a form of pure - heartedness. And Spongebob, in turn, sees Squidward's more vulnerable side. This mutual discovery leads to their love story.

Some good ones include 'The Day Homer and Bart Switched Roles'. In this story, they literally switch their daily routines and learn a lot about each other's lives. It's really interesting to see how they handle the change. There's also 'Homer's Lesson for Bart' which is about Homer teaching Bart an important life lesson in a very unique and unexpected way.
