What are some interesting ideas for a 'my singing monsters fanfic'?

First, think about your favorite monsters. Maybe you like the cute PomPom or the spooky Entbrat. Then, come up with a simple plot like a monster getting lost and the others going on a search. Just start writing down your ideas.

One idea could be a story where the monsters and aliens have to team up against an even greater threat from another dimension. Maybe a powerful interdimensional being that wants to conquer both Earth and the alien planets.

Perhaps a story where a young hero is on a quest to find the origin of the monsters in order to stop them from overrunning the world. They face many challenges and meet various strange creatures along the way. They might also discover that some of the monsters are not as evil as they seem and are actually being controlled by a greater evil force.

One idea could be a monster girl who is a mermaid and she has to adapt to living on land in an everyday human world. Maybe she gets a job at an aquarium and has comical encounters with visitors who don't know she's a real mermaid. Another could be a harpy monster girl trying to fit into a human school, dealing with things like flying in gym class and eating different food from what she's used to in her nest.

One idea could be exploring the backstories of the monsters more deeply. For example, what was Sulley's life like as a young monster? Another could be a story where Boo somehow returns to the monster world as an adult. Or a fanfiction about the monsters having to deal with a new kind of energy source other than screams.

One idea could be a story where Percy, the main character, discovers a new type of monster that has unique powers. He has to figure out how to communicate with it and whether it's a friend or foe. Another idea is a fanfic set in a different time period, like Percy in a medieval world full of monsters, and he has to use his skills in a whole new way. Maybe he becomes a knight who battles the most dangerous monsters.

One idea could be to create a story where the protagonist is a commoner who accidentally stumbles into the royal palace and catches the eye of the prince. The prince is initially intrigued by her non - royal ways and they start to develop a friendship that slowly turns into love. Another idea is to write about a modern - day girl who gets transported into the 'be my princess' world and has to navigate the complex rules of the court while also dealing with her growing feelings for one of the princes. A third idea could be a fanfic that focuses on the backstory of one of the princes, exploring his past traumas and how he overcomes them with the help of the main character.

One idea could be a crossover with 'Toy Story'. The monsters could accidentally enter Andy's room and interact with the toys. It would be hilarious to see Sulley and Woody trying to understand each other's worlds.

One idea could be an OC who is a new type of monster with a unique ability, like the power to change colors to blend in different sceneries in the human world. This would add an interesting twist to the story as they could use it for both scaring and befriending humans.

One idea could be creating an OC (original character) who is a misfit among the traditional monster students. For example, a small and timid monster in a school full of big, scary ones. The story could revolve around this OC trying to find their place and prove themselves in the university.
