Before moving, we were in a Zellers store and the kids found this book in the Vancouver 2010 Olympics section. It is called "Miga, Quatchi and Sumi" and it is a bilingual book. It tells the story of the mascots. We just read it this morning and it is cute with a little bit of Olympic and Paralympic games information. We really liked the illustrations and found that the authors/illustrators have written other books in a series called "The Octonauts".
The Vancouver 2010 Olympic masccots website has games and activities with the mascots too...We'll be checking those out later!
