What I ended up with was not a story about a rolling grape, but a book of twisted old sayings. I thought of about 20 to do, which should be enough for a picture book if some of them are spread across two pages, but I've only had time to think of clever twists for seven of them, which I think is enough to qualify as a first draft on Thanksgiving Day.
Here's a sampler of three. See if you can guess the original sayings they came from!
A hole in spoon gathers no sauce
A third grader’s candy’s worth two hundred bucks
A witch in slime says, “Fine!”
