Creating such a fanfic is a bad idea for multiple reasons. 'Spongebob' and 'Sandy' are iconic characters from a show that is known for its simplicity and humor aimed at kids. A 'pregnant' fanfic would not only be out of place in terms of the show's genre but also might lead to a wrong kind of fan following. It could also cause controversy and negative reactions from parents and fans who want to preserve the innocent nature of the 'Spongebob' universe.
I don't think there should be. 'Spongebob' and 'Sandy' are characters from a cartoon mainly aimed at kids. Having a 'pregnant' fanfic about them is really not in line with the nature of the show. It's important to respect the intended audience and the general tone of the original creation.
In a Spongebob and Sandy fanfic, the main focus is on Spongebob and Sandy. Spongebob, with his iconic laugh and his simple - minded yet endearing nature, is a key figure. Sandy, with her acorn - based lifestyle and her friendship with Spongebob, is equally important. Their friendship is what often forms the basis of the story, whether it's them sharing their different cultures (underwater vs land) or working together to solve a problem that affects both of them or their friends in Bikini Bottom.
It's popular because they are two very different characters. Spongebob is this goofy, fun - loving sponge, and Sandy is a smart and adventurous squirrel. Their differences create a lot of potential for interesting stories, like how they overcome cultural differences between Bikini Bottom and Sandy's treedome.
Mr. Krabs would probably be thinking about how this could be good for business. He might see it as an opportunity to create a new tourist attraction. Patrick would be really happy for Spongebob at first, but then he might get a bit jealous because he doesn't want to lose his best friend. Squidward would be extremely annoyed by all the commotion and the fact that he has to be part of the wedding in some way.
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.
Another idea is a story where Sandy wants to introduce some of her land - based inventions to the underwater world. Spongebob helps her with the process, but things go hilariously wrong at first. For example, a machine that is supposed to make the water around Bikini Bottom cleaner ends up making it all muddy. They then have to work together to fix it and learn a valuable lesson about testing things properly before using them in a new environment.
One thing that makes 'Spongebob and Sandy Lemon fanfic' unique is the blend of their different personalities. Spongebob is all bouncy and naive while Sandy is more scientific and tough. Fanfic writers can play with these traits, creating stories where they have to rely on each other's strengths. For example, in a fanfic, Sandy's scientific knowledge and Spongebob's optimism could combine to save Bikini Bottom from some new threat. It also allows for a different take on the underwater world of Spongebob, adding new elements like the 'lemon' aspect which might be a creative addition to the story.
It's a bad idea because it distorts the original story's message. 'Harry Potter' is about friendship, courage, and the fight against dark forces. A 'voldemort gets hermione pregnant' fanfic would introduce a disturbing and immoral concept. It also disrespects the characters as they are defined in the original work. Hermione is a strong, independent character who would never be involved with Voldemort in such a way, and Voldemort's character is too malevolent for any positive or appropriate relationship.
Spongebob could become more confident in his decision - making. For example, when it comes to using the lemons in their adventure, he might be the one to come up with a really creative idea that surprises Sandy. And Sandy could become more open to Spongebob's spontaneous ways. Usually she's very methodical, but in this fanfiction, she might start to enjoy the chaos that Spongebob often brings.
It could be really cute. They might have an underwater and land combined wedding. Spongebob would bring all his Bikini Bottom friends, and Sandy would have her treedome pals there. Maybe Mr. Krabs would be in charge of the 'food' which would be a mix of sea - food and acorns for Sandy. And Squidward would be reluctantly playing the clarinet at the ceremony.
