Peter becomes porcupine

How about discussing with children where emotions come from? What does anger feed on? Why are we calm and suddenly - boom - we're not anymore? Author Janaina Tokitaka tells the story of Pedro, an ordinary boy who goes on with his life as a child. However, when one of these things does not happen as he expected, Pedro becomes a porcupine. With a subtle and amusing metaphor about the changes in mood and sensations we experience in life – which many parents might call a “tantrum” or “trick”, the book invites the little reader to reflect on the origin of feelings.
