When a robot quokka drops by, a joey peeks out

A robot quokka with cameras for eyes ambles in among the real ones. It has come to see a joey who still rides in his mother's pouch. more

Quokkas are small wallabies, kangaroos scaled down, with round faces that always seem to be smiling. The spy was built for "Spy in the Wild 2" on PBS, which hides cameras inside lifelike animal robots so the real animals stay at ease and carry on as if no one is there. It mostly works.

The joey is just three months old. A small head pokes out of the pouch, and he takes in the strange visitor, glassy camera eyes and all, from close range. Like every quokka, he looks pleased about it.

For three months he has lived on his mother's milk. Now he's trying solid food, and the trouble is that he's getting too big for the pouch. It's already quite a squeeze to get out.

Once he's out, there's a big wide world to explore, and he tries it with a few little hops. He is going to need a lot of looking after.

Life outside the pouch means a lot to take in, and a lot to learn.

Then the spy sees another side of quokka life. For all their cuteness, quokkas will fight over food, especially tea tree. They stand up tall to pull leaves off the branches, and a good branch is worth a shove. Even the joey's mother is not keen to share.

With all that competition, the spy is on dangerous ground. At one point it gets knocked over. Then it gets itself back on its feet and carries on.

Its next move is a peace offering, and that seems to do the trick. For the joey, it has been quite enough adventure for one day.
