All kinds of stuff comes to life and dances in an Ub Iwerks cartoon, even tobacco juice spat out by Sailor Flip.
Then the juice spits out his own juice, and it starts dancing.
This is from the opening of “Stormy Seas” (1932). The animation of the scene on deck is interesting to watch frame-by-frame. The sailors are dancing to “Life On An Ocean Wave” on ones; the number of cycle drawings for the captain is different than the accordion-playing Flip but both are in time to the music.
