"The Dream Dragon always gives you happy dreams and they love and hug (yes, hug) almost everything. The only two things Dream Dragons hate are Nightmare Dragons and anyone who mistakes them for Cotton Dragons."
Dream Dragons look like big, fluffy clouds. The clouds are bright blue and happy pink. Their heads, tails, and legs are green. Dream Dragons always wear a smile on their faces as they prance around their habitats, keeping away other dragons nightmares.
