How do you drabble? Remember, your story's going to be seriously small, one scene, one event. If there’s backstory, it’s short and sweet. If there’s a happy (or otherwise) ever after, it has to be written in as few words as you can get away with. But you have to “show” the scene.
Telling—that’s where you say what happened. And you’re short of space; don’t bother with long descriptions. Showing is where you connect with the reader, where you drag them in so the telling can really tell. And that’s the scene.
Drabbled—shown and told in 100 words.
