The Shy Hedgehog's Sweet First Day

Create a heartwarming and healing storybook for children aged 3-5 about a shy little hedgehog named Doudou, who is anxious about his first day at school. He's afraid his sharp quills, which stand up when he's nervous, will prevent him from making new friends. The story, set in a magical forest kindergarten, gently explores themes of overcoming social anxiety, the beauty of being different, and creative problem-solving. Show how his new friends, a cheerful bear and a timid squirrel, help him by cleverly putting soft marshmallows on his spikes, turning his biggest fear into a sweet and unique trait. The style should be warm, comforting, and humorous, designed to ease children's back-to-school fears.
