Answer:
Mollie is one who likes material things. Her ribbons and her sugar cubes are something she uses to make others look at her and admire her. She was not concerned with what was happening to the animals, due to her vanity. What can I get out of this - her mantra.
Step-by-step explanation:
She eventually is a traitor - she is lured by the farmer near to animal farm due to the fact that he was providing her with sugar, etc. She could still have her material possessions and she no longer cared about the animals and how they were struggling.
