During an ocean voyage Betsy befriended Hank the Mule. Then, one night during a storm, the ship struck a rock and Betsy and Hank were thrown off the deck into the sea. Shortly after that it caught fire, blew up, and sank beneath the waves. They washed ashore in the Rose Kingdom. She teamed up with the Shaggy Man and several others, and together they went to the Nome King's Caverns to rescue the Shaggy Man's Brother. At the end of their adventure, Princess Ozma, at the urging of Dorothy Gale, brought Betsy and Hank to the Land of Oz to live in the Emerald City.
