In the magical land of Jik (where people are either lemon yellow or witchy green), bullies are a big problem. And Yellies think Greenies are weird! Fortunately for the pipsqueak Sparrow, some of the Witches in Jik are playfully kind. One of these, using some very sly magic, helps Sparrow (and his "heart friend" Lucy) to thwart and reform the mean bully Marvin. But it takes all the cleverness and bravery that Sparrow can muster.
