Quite Early One Planet

Quite Early One Planet - the arrival is a mythical tale about the origins of our Alphabet. It's alphabet creatures with feathers, scales and agile bodies. A living alphabet delivered to planet Earth 'from all parts of the universe' by a Great Weaver of Words.
It all begins with Argo a dust frog, who has sought refuge from all his fears on a desert oasis. One day at sundown, after years alone, Argo discovers a 'glow' in his shadow. Within the glow a voice whispers 'Argo set out to find your B, C and D, all of the others will follow, You will know them when you see them and they will know you'.
When all of the creatures find Argo and one another on planet earth the Weavers plan is nearly complete. In a shower of inspiration they discover their letter sounds and they're purpose is revealed "you will travel to the humans make yourselves seen and heard so the human's are able to make Word's...you my dear friends are an Alphabet, this you must never forget" whispers the Weaver to each one.
