Mother Nature Day

Mother Nature Day is a day of observance for the Smurfs in the EMPATH: The Luckiest Smurf story series. On that day, the Smurfs honor Mother Nature, the guardian of the forest, by helping her clean up the Smurf Forest of all sorts of garbage left behind in it by humans and other beings. It roughly corresponds to the human observance of Earth Day in that it takes place on April 22.

The day makes its first appearance in the framing parts of the story "In The Mercy Of Thy Enemy," in which Empath helps the Smurfs clean up the forest by pulverizing a pile of junk into particles of formless debris through the use of telekinesis.
