Mother Pluto is a Silly Symphonies cartoon released on November 14, 1936, directed by Wilfred Jackson.
She notices a butterfly and goes after it, after hiding all of the eggs under the hay in Pluto's doghouse so that no one will steal them.
When he notices one of the chicks upset after swallowing the grasshopper, he comforts it and starts to enjoy being a mother.
The Silly Symphony Sunday comic strip ran a two-month-long adaptation of Mother Pluto from August 14 to October 16, 1938.
