Cliff has pastel orange fur, mint green eyes, and purple and lavender wings. He has the pudginess, incisor tooth, and ears of a lemming mixed with the feet, nose, whiskers and tail of an opossum. He wears a light yellow and mint green explorer hat.
Cliff acts like a daredevil and has a never-give-up attitude. However, he is also very unlucky, as many dangers sweep him away, even with his perseverance. He loves to explore new places and is curious on learning about them. He hates it when anyone, especially Crocosaur, mistakes him for a rat or for 100% opossum.
