A tooth that becomes a happy tornado

Roxy is a vain little witch who loses a tooth, and this generates a shock to her self-esteem. She refuses to go to school, dance classes, shopping with her mother, and although she enjoys parties, she also refuses to attend them. Strangely enough, it seems that there is no need for her presence at these places, as her learning and skill development process continue in an even more efficient way. How is this even possible?
