One plot idea could be that they have to deal with the challenges of being young and pregnant while also facing Danny's ghost - fighting duties. Maybe they have to keep it a secret from their families and friends at first, adding a layer of mystery and stress. Another idea is that there could be some sort of ghostly influence on the pregnancy, either positive or negative, which leads to unexpected developments in the story.
A great plot idea could be that they discover the pregnancy has a special connection to an ancient prophecy in the ghost world. This would force them to search for answers and protection. They may encounter old enemies who now see this as an opportunity to get back at Danny. Sam could also struggle with her own identity as she transitions into motherhood, all while Danny tries to balance his superhero life with being a supportive partner. The story could show their relationship evolving as they face these various challenges together.
Well, one aspect could be the role of their superpowers in the pregnancy. Perhaps Sam's pregnancy has some unexpected effects on Danny's powers or vice versa. And the story could also delve into how they prepare for the new arrival in a world full of ghosts and other supernatural elements.
A really cool plot could be that Sam is given a rare plant seed by a mysterious figure. When she plants it, it grows into a giant, sentient plant. Danny at first is wary of it, but they soon find out that the plant is actually friendly and has some knowledge about Danny's ghost powers. Together, they use the plant's abilities to fight off a powerful ghost that is threatening their city.
A plot could be that a magical spell gone wrong makes Sam and Danny age down to babies. Tucker discovers that there's a time limit to reverse the spell. Meanwhile, the two babies are exploring the world in a very different way, seeing things from a new perspective. This could lead to some heartwarming and funny interactions with their families and friends as they all try to solve the mystery of the spell.
The plot could involve some sort of mystery related to the pregnancy. Like, there could be a ghostly force that is either helping or hindering the pregnancy. And they have to figure out what it is and how to deal with it. Also, their friends like Tucker could play important roles in supporting them.
One idea could be that Danny and Sam travel back to the founding of Amity Park and accidentally change something small that has huge consequences in the present. For example, they might stop the first settler from building in a certain spot, which then changes the layout of the whole town and where ghosts can enter from in modern times.
One great fanfiction could be 'Sam's New Chapter' where the story delves into how Sam's pregnancy changes her relationship with Danny. It shows their growth as characters as they face this new situation together. Another one might be 'Sam's Unexpected Journey' which focuses on Sam's own self - discovery during her pregnancy and how she navigates the challenges.
Some fanfictions might focus on the challenges a pregnant Danny (if that's the concept) would face in the human and ghost worlds. For example, he'd have to hide his situation from some in the human world while also dealing with any potential threats from the ghost world that could endanger him and the baby. And then there are the emotional aspects, like Danny's own fears and hopes about becoming a father.
One interesting story could be about Danny and Sam going on a ghost - hunting adventure together. They might discover a new type of ghost that has unique powers and they have to figure out how to defeat it using their combined skills.
One idea could be that Danny and Sam have kids in the future and their kids inherit Danny's ghost powers. The story could focus on how they learn to control their powers while also dealing with normal kid stuff like school and making friends. It would be interesting to see how Sam, as a mom, guides them through this.
Maybe in the fanfiction, Rachel and Sam are in a secret relationship when they find out about the pregnancy. They then have to decide whether to go public or keep it a secret for a while longer. This could lead to a lot of drama as they try to hide it from their friends who might not approve. Another aspect could be their journey to prenatal classes, where they meet other expecting couples and learn more about pregnancy and childbirth.
