A minisaga is a very short story that is only 50 words long. It is like a mini adventure that you can read quickly and easily. It's like writing a super-short story that tells a big story in a few words. Imagine telling a whole story in just one or two sentences, like "Once upon a time, there was a magical unicorn who lived in a castle made of rainbows." That's a minisaga! You can use your imagination to come up with all kinds of creative and exciting stories, but you have to keep it very short and sweet.
