Stuart’s mother is extremely over protective about him and this increases when he narrowly escapes injury in a soccer game. George has a new friend, Will, so he feels lonely. Stuart rescues a canary, Margalo, from a falcon. She moves in with the Littles, but one day she is not to be found so, so Stuart and Snowbell set out across the city to find her while George covers for Stuart (the first time he's had to lie)
