Oliver's Mistake is an upcoming episode. It is based on a magazine of the same name.


Percy sees some giraffes when he takes visitors to the Sodor Animal Park, and tells Oliver that evening. Oliver wants to see them for himself but is sent to the harbour, where he sees things with long necks and long legs which fit Percy's description of the giraffes. In the morning Oliver discovers they are cranes, but gets to see a real giraffe when he takes animal feed to Sodor Animal Park.
