Title banner reading 'The Hilarious Adventures of Sheldon & Fiona' in colorful, textured letters with a yellow scroll background.

The Sheldon & Fiona Series introduces Sheldon, an anxious turtle presenting with features of Autism and Fiona, a high-energy, seat of the pants firefly presenting with features of ADHD. They take the world by storm in this charming and hilarious series. Fiona encourages Sheldon to get "out of his shell" or to get less "shelled-in" and to try new and exhilarating experiences. Meanwhile, the rigid, detail-oriented and routine-loving Sheldon reminds Fiona to reel it in sometimes. Despite their differences, the two celebrate the beauty of friendship in the most fun, empathic and meaningful ways.
