The Cedar Pencil Sharpener

Tommy has a very special pencil sharpener. Every time he takes it out, the smell of cedar fills the classroom. But his pencil sharpener is special for another reason too: if you put you ear to the pencil hole, you hear the rustling of cedar trees. But these last few days the pencil sharpener seems to have lost its magic abilities. Is something wrong with it or has something happened to the cedar tree forest? The children decide to take action immediately and save the forest. (Level: 2.000 Leagues)
