Plot
Cranky was kept working through the day and night, and never gets any rest. One day, he becomes frustrated with Salty's tales, he accidentally drops a load of pipes onto the rails, knocking over a shed and trapping Salty, Bill, and Ben at the docks. Salty decides to pass the time by telling sea stories to the delighted twins, but poor Cranky was unable to get any rest even when he is not working. He was awake all night, until Harvey finally clears away the mess in the morning. Cranky is so relieved that Salty won't have to tell any more stories, he stops being cranky and is very polite to all the engines, much to their surprise. But soon he just cannot help himself and dumps some more pipes onto the tracks. All the engines laugh, except for Cranky, who just stays cranky.
