Little Bo-Peep was one of the six parrots that were trained by John Silver to speak the clues that leaded to the hidden painting that was smuggled by Silver, and was owned by Irma Waggoner. Its line in the clue was, "Little Bo-Peep has lost her sheep and doesn't know where to find it. Call on Sherlock Holmes!" It meant that the graveyard's address was 222B Baker Street, if Billy Shakesphere's clue was solved along with it.
After John Silver had fled to California after smuggling the painting of the shepherdess, he started living in Ramos Sanchez's house. After getting an idea from the picture that was painted above the shepherdess' painting, Silver bought seven parrots with "pretty yellow heads" and seven cages. He then began teaching them their individual riddles.
After Silver had died, Sanchez waited for the "fat man" who Silver said would come. However, the man didn't come, and all the parrots, including Bo-Peep, were sold to different people.
After Claudius had escaped from Malcolm Fentriss' house, he was going through Waggoner's house. Then, he stole Bo-Peep, as Waggoner had gone to the store to buy sunflower seeds for Bo-Peep.
After the entire mystery was solved, Claudius returned Bo-Peep to her owner, Waggoner.
- Bo-Peep's speech was Part 1 in the riddle.
