I'm not sure exactly what happens in this story as I haven't read it. But I can imagine that it might be about a monster showing up at school and causing chaos among the students and teachers.
The main idea could be how the presence of an extraordinary being like a monster disrupts and changes the normal routine at school. It might show how the students and teachers react to this out - of - the - ordinary situation, whether they adapt, panic, or try to find a solution to deal with the monster.
The story might start with the chaos that the monster brings to the school. It could disrupt classes, make students run around in fear. But as the story progresses, the monster might show its kind side. For example, it could help a bullied student, which changes everyone's perception of it. And in the end, it might be accepted as a part of the school community.
In this story, the monster is obviously one of the main characters. Then, there must be some key students, like the bravest one who tries to approach the monster first, and the teachers who are responsible for keeping everyone safe and dealing with the unexpected situation. These characters together form the main part of the story.
It could be about a monster's unexpected visit to a school. Maybe it causes chaos among the students and teachers, or perhaps it has a special reason for coming, like looking for a lost item or a friend.
Obviously, the monster is one of the main characters. And probably some students and teachers in the school as well, since they are likely to have interactions with the monster.
Use colorful pictures related to the events in the story. For example, if you're writing about a school field trip, include a picture of the place they visited.
