How to use this prompt
The octopus reading a book is the detail that makes this a story, not just a setting. A library underwater is a curiosity; an octopus using it is a narrative. The tall wooden bookshelves filled with books give the space its human scale; metal shelves would read as a lab, not a library. The large round window with light filtering down from the surface gives the scene its depth and light source; a flat ceiling would make it a room, not an ocean floor. Schools of small fish swimming between the shelves add life and movement without competing with the octopus.
Variations to try
- A whale swimming past the window in the background
- A closer view of the octopus turning a page
