Answer: I bright as the sun and I'm happy as a quokka.
Explanation: A simile is a comparison of 2 like things using the words "like" or "as." In my sentence, I said I'm bright as the sun. "Bright" and "sun" are alike because the sun is bright. "Happy" and "Quokka" are alike because the quokka is known as the happiest animal because of its big grins and animals can be peaceful and happy.
