When Florence went into the hidden compartment and found the stuffed rabbit, the rabbit played a recorded song. At this point in history, toys only contained small music boxes, which played chiming music. The closest thing was the "Lioretgraph Jumeau" which sang a maximum of 35 words using a small phonograph. More advanced singing toys didn't make their appearance until the late 1930's and early 40's.
