Lorax
The Lorax is a mystical, orange, furry humanoid creature with a prominent yellow mustache who serves as the guardian of the Truffula forest in the 2012 animated film adaptation of Dr. Seuss's story. He is introduced as the voice for the trees, speaking out against the Once-ler's destruction of the forest after the Once-ler cuts down a Truffula Tree, which summons him. Voiced by Danny DeVito, the Lorax is portrayed as grumpy yet deeply passionate, tirelessly warning the Once-ler of the environmental consequences of his actions and pleading for the forest's protection.
