What are some interesting plot ideas for Danny and Sam in a kids' time travel fanfiction?

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 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.

Well, perhaps a plot where they get married in a secret ghost - friendly ceremony. Then, they embark on a journey to find a way to make the Ghost Zone and the human world co - exist peacefully. This could involve many adventures and meeting different kinds of spirits along the way. They also have to deal with the reactions of their friends and family to their new life goals.

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.

It could be an evil time - traveling wizard. He's jealous of Danny's powers and wants to steal them. He uses his magic to create all sorts of obstacles for Danny and Sam as they travel through time, trying to prevent them from getting back to their own time.

One idea could be that Danny and Ember accidentally travel back to the founding of Amity Park. They could witness the early settlers dealing with strange ghostly phenomena and have to figure out how to not disrupt the timeline while also helping the settlers. Another plot could be that they travel to a future Amity Park that is overrun by a new type of ghostly threat, and they bring back knowledge to prevent it in their own time. Or they could travel to a time when Danny's parents were kids and see how their obsession with ghosts started.

They might have adventures like exploring ancient civilizations. Maybe they meet historical figures and learn from them. For example, they could meet Leonardo da Vinci and watch him paint. Or they could end up in a prehistoric era and see dinosaurs.

Perhaps in the fanfiction, Danny discovers that there is a threat in the past that could change the future in a very bad way. He, along with Sam and Dani, time - travels to stop it. Along the way, they meet younger versions of their friends and family. Dani starts to understand more about her family's history and her own place in it. Sam has to deal with the differences in the past's social norms compared to their time. And Danny battles villains from the past who are trying to take over the future using the knowledge of time travel they accidentally introduced.

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.

Danny's adventurous spirit would make him eager to jump into different time periods and experience new things. However, Sam's more reserved nature would ensure they think about the consequences first. For instance, when they come across a strange time - based phenomenon, Danny might want to rush in while Sam would want to study it more before acting.
