WANTED! New Dad.

Every orphan needs a dad, so why not use Billy's? He's in the bush somewhere, so Billy leads his new friends into the never–never to find him: nine young shoeless orphans, ten if you include Amber, plus four dogs and a baby kangaroo.
What could possibly go wrong? How about a kidnapping? A spear–pointed stand–off with the police? Or what about a run–in with a dangerous gang?
