What did the wicked witch of the west send to Dorothy?

The Wicked Witch of the West sent a pack of wolves, crows, and later, a swarm of flying monkeys to capture Dorothy and her friends as they traveled through Oz. Most notably, she used the flying monkeys to abduct Dorothy and Toto in her attempt to retrieve the magical ruby slippers. Her actions were driven by her desire to reclaim the slippers, which held great power.
