After just meeting Tik-Tok, Dorothy winds him up, and then he bows, and raises his hat. As he bows a crewmember can clearly be seen crouched behind him.
Here are some interesting tidbits about where some of the aspects of the movie came from, which is a compilation of the books following the first. Jack Pumpkinhead, the Powder of Life, the Gump, Mombi, Ozma (Tip) and the escape off the top of the roof all come from 'The Marvelous Land of Oz'. The multiple heads angle, the Gnome King's Nick-Nack game, the chicken coop, Billina, and Tik-Tok all come from 'Ozma of Oz'. The tunnel under the Deadly Desert that Mombi uses to get to the Gnome King seems to come from 'The Emerald City Of Oz'.
