Si is the Siren of Sounds, she lives in the garden of letters, and has a book in which her friends, the vowels, live. In each episode, they tell us how they sound together with other letters, and how the words are made.

Finding a good name for a show is usually a headache, but in this case, it was the first thing its director, Betty Cisneros, told me as an idea. I loved it. Great start.

From then on everything flowed wonderfully. We created a graphic style for the vowels and animations that were super cute and colorful.
