It is not common for a Koala bear to give births to twins. However, in this instance the mom was hit by a passing car and subsequently died. The kind-hearted driver stopped and took the mother to the local vet, unsure if she was dead or unconscious. This was where it was discovered, that she had twins in her pouch.
