Six Little Pixies in my Heart is the story of Tommy.  Tired of hearing that he is too sensitive, he decides to set free the six little pixies that live in his heart and who are responsible for his hyper-sensitivity: Merry, Shaky, Teary, Stunny, Ragey, Picky.
Helping him is the little witch Renza, a mysterious inhabitant of his refrigerator.  At Tommy’s request, she transforms him into an insensitive child who is indifferent to everything that surrounds and happens to him.  The six little pixies decide to abandon the child’s heart and go their separate ways, each one looking for happiness in his/her own dream place, agreeing to meet back at Tommy’s home after exactly one month.
Everyone leaves, except Merry who already has everything the others want, and Shaky who lacks courage and does not venture to distant places.  Instead he remains hidden alone in Tommy’s room where he discovers something really important: Renza used to be a fairy named Serenella who lived with the pixies in the heart of the child.  She was turned into a wicked witch by Gelone the wizard.
Once reunited, the pixies remember the fairy who once took care of them, and therefore do not delay in freeing her from the magician’s spell.  All together they return home to Tommy’s heart, convinced that there is nothing wrong with being sensitive and experiencing many different emotions.
