I barely remember this story about a bubble suddenly appearing in a kingdom and everyone from the farmer on up to the king believes the bubble to be trouble. There's lots of rhyming with the word bubble and other words as well. In the end a little rescues the King from inside the bubble by popping it. I heard this story at a library story telling day when I was 10 years old. Now I want to retell it in full but I can seem to find it on the net by any name. I'm hoping the brain pan of this wonderful site may hold the answer. Thanks.
