To close the film, Disney wanted for a piece that was "emotionally equivalent" to the Night on Bald Mountain and Ave Maria segments that closed Fantasia. Disney chose the The Firebirdas the piece to use after "half a dozen" others were scrapped, including Symphony No. 9 by Beethoven and the "Hallelujah Chorus" from Messiah by Handel. Disney thought of the idea of the Earth's destruction and renewal after passing Mount St. Helens following its eruption in 1980. French twins Paul and Gaëtan Brizzi from Disney's Paris studio were hired to direct the segment. The Sprite is a Dryad-like creature from Greek mythology. Her form changes six times; she is introduced as a Water Sprite who plants flowers as a Flower Sprite. She becomes a Neutral Sprite where her growth trail stops and an Ash Sprite when the forest has been destroyed. The segment ends with her as a Rain-Wave Sprite, followed by the Grass Sprite. The segment originally ended with the Sprite in the form of a flowing river that rises up into the sky and transforms into a Sun Sprite, but this was abandoned. The antlers on the elk were produced with CGI and placed on top of its body that was drawn traditionally. The segment was produced using Houdini animation software.
