Which of the following characters is NOT from 'The Whipping Boy'?

In "The Whipping Boy" by Sid Fleischman, the characters are primarily focused around a young boy named Jemmy, who serves as the whipping boy for Prince Horace, the spoiled and mischievous prince. Their adventures and challenges form the core of the story. Betsy is also mentioned as a character in the narrative, supporting the story's development.

Motormouth Maybelle, however, is a character from the musical "Hairspray," which is unrelated to "The Whipping Boy." This distinction makes clear that she does not belong to the world created by Fleischman. In contrast, both Jemmy and Prince Horace are central figures in "The Whipping Boy," actively involved in the story's key events, thus confirming that Motormouth Maybelle is the character that does not fit within this context.
