Of all the characters in this series, Trot and Cap'n Bill were two that took a little deciding on when to cover them. They first appeared in the Oz series in 1915, in the book
The Scarecrow of Oz. But Baum writes in his introduction that readers requested that they be "admitted to the Land of Oz," so readers in 1915 knew who they were. However, to a novice reader reading the Baum books for the first time chronologically, these two are strangers.
Trot and Cap'n Bill had actually been introduced in 1911 in the book
The Sea Fairies. Mayre "Trot" Griffiths lives with her mother, who boards Bill Wheedles, a retired peg-legged sailor who cares for Trot, serving as a surrogate father as her actual father is often away at sea. Trot is a curious but strongly opinionated little girl, while Cap'n Bill is a grizzled old sun-tanned sailor who fears only what he can't defend Trot from.
The two go exploring together, and the plot of
The Sea Fairies finds them being turned into mer-people so they can visit with the mermaids and the sea creatures. They become friends with the mermaids and King Anko, the great Sea Serpent. Trot is even given a ring to summon the mermaids when she needs help near the water.
To attempt to boost sales, Baum's much more substantial sequel,
Sky Island, brought in Button-Bright and Polychrome from
The Road to Oz, tying the series to the Oz books. Button-Bright arrives via a flying Magic Umbrella to Trot and Cap'n Bill's home. He visits with them and shows them how the Umbrella works. By accident, it takes them to an island in the Sky, where they are made prisoner by the Boolooroo of the Blues. Finally, they escape to the Pink side of the Island, where they are almost executed until Polychrome arrives in the nick of time to save them, using a law that makes Trot the new queen of the Pinkies. With the help of the Pinkies and a little magic, the Blues are conquered, making Trot the "boss." After recovering the Umbrella, Trot, Cap'n Bill and Button-Bright return to Trot's home in California.
The series was not selling as well as the Oz books, forcing Baum to produce
The Patchwork Girl of Oz for 1913. Reilly & Britton, the publishers, suggested that Baum alternate between Oz and Trot's adventures, but Baum decided to only produce Oz books. Yet it seems Baum's non-Oz fantasies had its fans, spurring him to make Trot the third and final little girl to visit and stay in the Land of Oz.
There's some debate as to whether or not
The Scarecrow of Oz was a revised third Trot book. Oz proper doesn't appear in the story for several chapters, but the book finds Trot and Cap'n Bill being sent underground by a whirlpool. If
The Sea Fairies represented the element of water, and
Sky Island represented the element of air, did
Scarecrow represent the element of earth?
Yet a counter argument rises in that
The Sea Fairies and
Sky Island take their time to get the story started, while
Scarecrow begins with Trot and Cap'n Bill rowing out into the water and being caught in a whirlpool. Yet it is possible that Baum revised the opening and chopped off an opening chapter or two.
Whatever the case,
The Scarecrow of Oz finds Trot and Cap'n Bill going underground thanks to a whirlpool and arriving on an island inhabited by a pessimistic old man. With the help of Flipper the Ork, they fly away to the Valley of Mo, and from there meet Button-Bright again, and then fly over the desert to the Land of Oz, unfortunately arriving in Jinxland. King Krewl has Cap'n Bill transformed into a grasshopper while Trot is left to wander around Jinxland. The Scarecrow intervenes and defeats King Krewl and Blinkie the Witch with the help of the Orks, and then escorts Trot and Cap'n Bill to Glinda's palace.
Trot then becomes the third girl from America to live with Ozma in the palace, joining Dorothy and the Wizard's search party to find Ozma in
The Lost Princess of Oz. However, she and Cap'n Bill have another adventure in
The Magic of Oz as they try to get a magic flower for Ozma's birthday. They have a couple close shaves on the way, and need the Wizard's help to finish the task.
John R. Neill was a little loose about Trot's hair color. She almost looks like Dorothy in some
Scarecrow pictures, but seemingly, the generally accepted hair colors by fans of the books are that Dorothy is blonde, Ozma is a brunette, Betsy has auburn hair, and Trot has black. (Remember, generally accepted. Anyone wishing to change this up for their own work or ideas is welcome to.)
Trot and Cap'n Bill generally play minor roles in the rest of the Famous Forty Oz books. Cap'n Bill makes Trot a wooden doll from a tree that princess Peg Amy was transformed into, which is stolen, enlarged, and brought to life by Ruggedo in
Kabumpo in Oz, before she is restored to her original form. In
The Giant Horse of Oz, looking for a maiden to satisfy Quiberon, Trot is kidnapped by Akbad. She escapes with Benny and the Scarecrow, who were carried away. In the Famous Forty + book
The Wicked Witch of Oz, the Witch Singra accidentally turns Trot into a piece of cheese when she meant to do it to Dorothy. (She is, of course, restored by story's end.)
Outside of the Famous Forty, Trot has had more adventures. In the late Marc Haas'
The Medicine Man of Oz, many of the
Giant Horse crew reunites for a new adventure, including Trot. Eric Shanower originally conceived
The Enchanted Apples of Oz as a Trot and Cap'n Bill tale, and later cowrote
Trot of Oz with Glenn Ingersoll. Finally, David Tai offers a Trot who is a little more impetuous than her Famous Forty appearances to give her a more distinctive personality. So far, David's only published story with Trot is in
Oziana 2008 in "Executive Decisions." He's written more stories that await publication, however, many of which have his take on Betsy and Trot bouncing off of each other.
