One idea could be that the Goonies find an ancient map leading to a lost underwater city. They then have to build a special submarine to reach it. Along the way, they face new villains who also want to claim the treasures of the underwater city.
Chunk is always a great character to include. His funny and sometimes clumsy nature can add a lot of humor to the story. For example, he could accidentally trigger a booby - trap while the Goonies are exploring a new cave, but then also be the one to find a way out of it in a really unexpected way.
One common theme is friendship. Since The Goonies is about a group of friends, fan fictions often explore the bond between the characters, especially how they interact with Sloth Fratelli. Another theme could be adventure. They might continue the adventure that started in the movie.
Social media groups can also be a good source. There are groups on Facebook or Reddit that focus on The Goonies. Members might post their fan fictions or know where to find them. However, make sure to check the group rules before asking for fan fictions.
The 'Goonies Novel' is likely about the adventures of a group of kids, probably filled with mystery, treasure hunting and friendship. Just like the movie, it might tell the story of the Goonies as they face various challenges and try to achieve a certain goal.
Definitely not. The Goonies is a fictional tale. It was crafted to give viewers a thrilling and fun experience, not based on any real events or people.
