When a koala is born, it is only about the size of a large jelly bean and is not yet fully developed. Even after it starts leaving the pouch, a joey will return to the pouch when it wants to hide or sleep. After it grows too large for the pouch, the joey climbs onto its mother’s back and holds on with strong hands and feet. After about a year, it can live alone in the trees.
