Curious Sofia explores why sleep is important and her friend, Mr. Tie, helps her find the answers with the help of a magical tie.

Like any other kid, Sofia loves to play and gets really sad when it's time to go home and sleep. Her parents keep insisting on the importance of sleep but she struggles to understand why sleep is so important. She calls on her friend - Mr. Tie, a dog with a magical tie to help her understand what happens to her body when she sleeps.

Mr. Tie uncovers the amazing benefits of sleep, from mending our bruises and balancing our emotions to making space for new memories in our brains. He explains how, each night, an invisible army gets to work, repairing our bodies, strengthening our immune system, and helping us fight off germs and bacteria.

Sofia and Mr. Tie discover that sleep isn't just a routine part of the day; it's an exciting adventure that prepares them for anything that comes their way.
