Hippo: The one who sleeps 20 hours a day! He only wakes up to collect his food
Sloth: An aptly named animal that also sleeps 20 hours a day. He prefers to sleep hanging on a tree and moves slowly. It may take him several hours to do something and then he rests more time than he spent working.
Panda: My favorite animal, which is threatened with extinction: (, it moves slowly and sleeps a lot! However, it never likes confinement, but rather loves freedom, it sleeps more than it wakes up!
