Answer: Marsupials! Like kangaroos, the lovable koala keeps its babies in its pouch, like kangaroos. Unlike kangaroos, Koala pouches can't be seen. No wonder Koalas have good climbing power, they have rounded feet. A newborn koala is the size of a jellybean! It has no hair, no ears, and is blind. Joeys crawl into their mother's pouch immediately after birth and stays there for about half a year.
