Trivia / The Bobbsey Twins

• Follow the Leader:
  • The success of the series led to the creation of "The Happy Hollisters", which (although the Hollisters were five kids, and none of them twins) copied a lot of the details, such as the small misadventures and scrapes occasionally leading into bigger mysteries, loving and involved parents, a resident "bad boy bully" who shows up to be mean from time to time, and even a cat and a dog.
  • The Bobbseys themselves followed suit when fellow Stratemeyer Syndicate series, The Hardy Boys and Nancy Drew grew popular, and the Bobbsey books underwent a gentle Genre Shift to become a lot more about mysteries, hidden treasures and suspicious people pulling off strange schemes — though with a couple of surprisingly Darker and Edgier examples very late in the series, it never really lost its "fun family adventures" tone.
