It is a busy week for Brolga as he embarks on the tricky art of toilet training orphan kangaroos Rex and Ruby. Fellow kangaroo carers in Alice Springs come up with innovative ways to look after the orphans in their care, from Elvis, a plucky little orphan who will not stay put, to Lick Lick, who has being taught to use a baby toy as physiotherapy. Brolga takes part in a radio interview to raise awareness of his work, but ends up answering questions of a more personal nature. Meanwhile, out in the sanctuary, he turns detective to find out why mob boss Roger is in such a bad mood.
