Koalas are not bears. They do have the word "bear" in the name but they are not bears, they are mammals. Koalas sleep for 22 hours a day. If you do not know, baby koalas are so cute they probably are the cutest things on earth. If you see the new exhibit at the zoo for the koalas you can meet the 2 new koalas [ who flew v.i.p here]. They will look at you and you will love them from the start!
