MeMo and BaBa are jumping in puddles and notice a rainbow in the sky. It’s beautiful and colourful, but where does it end? They head to the Play Tree to find the rainbow’s end and draw pictures of rainbows. BaBa thinks the rainbow ends with the Yummies, but MeMo thinks it ends with Elewhale. They embark on a journey to find more rainbows all over Planet BeddyByes.
