In 'The Lorax', what are the furry creatures that eat Truffula fruits called?

In “The Lorax”, the furry creatures that eat Truffula fruits are called Bar-ba-loots.

Bar-ba-loots are small, bear-like creatures living in the Truffula forest. They feed on the fruit of the Truffula trees, making them one of the first creatures affected when the Once-ler begins cutting the trees down to manufacture Thneeds. As the forest is destroyed, the Bar-ba-loots lose their food supply and are forced to leave.

They are easy to confuse with the Lorax’s other forest companions. Humming-Fish live in the polluted pond and eventually swim away, while Swomee-Swans flee after the air becomes contaminated by factory smoke. The Bar-ba-loots therefore represent the effect of deforestation and habitat loss, rather than water or air pollution alone.

The name is usually written “Bar-ba-loots,” with hyphens, in references to Dr. Seuss’s 1971 book. Their story helps show that environmental damage spreads through an entire ecosystem.
