Emily's Search for a Best Friend

Emily sets out on her jobs for the day as the only engine without a partner. She encounters various engines who are busy with their own tasks and feels left out. In her search for a best friend, she asks Phillip, Mariam, Henry, and Edward to join her, only to realize that she cannot choose just one best friend. As Emily rushes back to the docks to collect the sand for the sculpture, she realizes that her friends have brought the sand trucks for her. The sand sculpture is unveiled, featuring all the engines of the steam team, and Emily realizes that she didn't need one best friend when she had so many.
