Plot

Mother Nature's getting a sex-change!?

Tropes

Blood from the Mouth: The flowers suddenly cough some up during the song number at the beginning before informing Chauncey of Mother Nature's transitioning.
Self-Surgery: A whole scene from this episode is dedicated to Mother Nature proceeding with her (his?) own sex-change surgery and disposing of the scraps in a box labeled "Lady Parts". It's just a puppet, but still.
Vocal Dissonance: The mother in the "Segregation" segment is voiced by a man.
