Bar-ba-loots are bear-like creatures that live in the forest filled with Truffula Trees. In the movie, while they appear intimidating, they are really just harmless creatures. And apparently very light weight, as Chet and Brett tried playing football with one. The Once-ler begins to form a type of friendship with the Bar-ba-loots, even nicknaming one of them. But when his Thneed business grows, he quickly forgets them and destroys the trees that provided them fruit. When they leave with the animals (including the Once-ler's mule Melvin), it hurts the Once-ler, helping him realize the damage he has done.
