The vowels, A, E, I, O, and U know they are important! They know vowels are always needed to make words, so they form a cool club, the Wow Vowel club. Each vowel gives examples of words it can make. But every time they do anything, there is a mysterious character who intrudes! Some other letter of the alphabet says it is a vowel too! It seems impossible until the mystery character is revealed: the letter Y! The other vowels gladly invite Y into their club and add his rhyme to their poem to celebrate.
