Tissywoo is a little girl who is about to start school for the first time. She is excited but also anxious. Her anxiety turns into a little worry monster. As Tissywoo keeps worrying, more monsters begin to appear. They grow so big they threaten to overwhelm her! Scared and frightened Tissywoo remembers something her mother told her to do when the worry monsters come along.
Tissywoo uses breathing techniques to calm herself; using slow deep breaths in and out. The more she controls her breathing the better she feels, and the worry monsters grow smaller and disappear.
