/**

Fool me once, shame on you. Fool me twice, shame on me. Fool me three times, and I am a Donkey.

Donkey, Shrek's best friend, is a lovable and talkative character. He is a small, gray donkey with expressive eyes and a big smile. 

Donkey is known for his energetic and outgoing personality, always eager to make friends and engage in conversation. 

Let's use his energy and make $DONKEY reach the moon!
