Eeyore Donkey is a fictional character from A.A. Milne's "Winnie the Pooh" series. He is a gloomy, pessimistic, and somewhat sarcastic donkey who often loses his tail. Despite his melancholic demeanor, Eeyore is a loyal friend to Pooh and the other inhabitants of the Hundred Acre Wood. His characteristic downbeat attitude is often a source of both humor and sympathy in the stories. Eeyore's role is to provide a contrast to the more upbeat characters, highlighting the importance of friendship and understanding in the face of adversity.
