The Once-ler tells the boy of his arrival in a beautiful valley containing a forest of Truffula trees and a range of animals. The Once-ler, having long searched for such a tree as the Truffula, chops one down and uses its silk-like foliage to knit a Thneed, an impossibly versatile garment. The Lorax, who "speaks for the trees" as they have no tongues, emerges from the stump of the Truffula and voices his disapproval both of the sacrifice of the tree and of the Thneed itself. However, the first other person to happen by purchases the Thneed for $3. 98, so the Once-ler is encouraged and starts a business making and selling Thneeds.
