One koala is pretty cute, so two koala babies are almost impossibly cute and a rare set of koala twins were born at a wildlife park in Australia.

The koala twins may be only the fourth to be born in captivity.

"To put it into perspective, I'd have to say it'd be almost like me actually giving birth," park owner Darren Tilley said.

The Wildlife Wonderland Park officials in Bass, Australia, were surprised to see Mom Bussy throwing baby Kailla out of her pouch, and even more surprised when a second koala poked its head out.

There's only room for one koala in a mother's pouch, so Kailla is being cared for and fed every two hours by park staff.

Her yet-to-be named brother or sister is safe inside the pouch.

And little Kailla is battling the odds too, surviving well so far outside the pouch.

The orphaned baby has a one in 10,000 chance of survival, but staff say both brother and sister are doing fine.
