Isabella (also known as the Once-ler's Mother) is one of the two main antagonists (alongside Aloysius O'Hare) of the 2012 movie adaption of The Lorax, and the greedy and pessimistic mother of The Once-ler. She dubs her most successful child business-wise as her "favorite child."


Isabella is a cruel, manipulative, mean, and uncaring mother that uses her son as a toy. she is also seen to be quite unsupportive as she is seen harassing the once-ler when he is ready to go off.

Isabella wears Black glasses, a red bow, gray eye liner, and has blonde puffy hair. She is seen wearing a hound scarf around her neck. She also wears blue furry boots and has a purple polka dot shirt and a gene dress.

In The Lorax

She went with her family to help the Once-ler make thneeds. It was her and the rest of the family that persuaded him to chop trees down rather than harvest their tufts. She was proud of him only when he became greedy and self-righteous. But when the Thneed factory closed because of the lack of trees, she disowned him and told Brett that he was now her favorite child. She then left the Once-ler to be a hermit.

Current Life

Isabella's current life is unknown. We can presume that she is either deceased or very old (based on the Once-ler's age).


  • Once-ler - Isabella treats him very badly. She had told him that he would fail in his life for untold reasons. When his business fails she promotes Brett to her favorite child.
  • Brett and Chet - The mother seems to treat them both nice usually. She promoted the former to her favorite child, when the Once-ler failed.
  • Aunt Grizelda - their not seen interacting that much but it’s presumed that they have swell relationship.
  • Uncle Budd - like the once-ler Isabella treats uncle budd like a toy rather than family as she is seen walking on him when she gets out of the rv, the only difference is that isabella doesn’t treat him as badly as the once-ler.
