Red-Headed Baby

Red-Headed Baby is the sixth title in the Merrie Melodies series. The short was released as early as December 18, 1931. It is directed by Rudolf Ising.

Plot

Around Christmas Eve, a toymaker creates a red-haired doll, who, after he departs, comes to life along with the other toys; she subsequently breaks into singing the titular song, in the process meeting a soldier who instantly falls for her.
However, a massive and thuggish spider also has fallen for the doll. He kidnaps her and beats the sawdust out of the soldier. The soldier fills his body up again and defeats the spider using a toy train. All the toys rejoice and the doll and the soldier reunite as the titular song reprises, ending the cartoon.
