This prompt is going to be a bit silly, but can be a good way to get the creativity going.
Pick a set or words and try to find as many rhyming words as possible. Once you’ve got your list, create a scene in which all of the words are featured.
Hen, Pen, Den, Wren, and so forth.
I’m off to write a story about a Wren that makes friends with a hen, they run away to a den and write their farewell note with a pen… 😉
