Once there was a bird in the Amazon Forest. He was a sparrow who had very big wings so he could glide three miles. One day when he was chasing an electric eel he got stuck in an underwater cave and couldn’t breathe until he swam up to the dry land. He began to explore the amazing cave system but soon he got completely lost and began to cry miserably for help. A vampire bat flying out of the cave rescued the relieved sparrow.
