A free trip to the Northern Territory! Sounds good, thinks Marcus -- "Mucus" to his sister Rose. But when his best friend Dylan joins the family holiday, mayhem is not far away.
Blacky the farting dog, back in his second adventure, has a mission that Marcus and Dylan can't refuse. Trouble is, this mission involves a monstrous saltwater crocodile who would much rather chomp on a human for dinner than have a civilized conversation. Of course, there's also the small matter of a giant big-game hunter on a collision course with our heroes. And will Marcus be any match for his mean older sister Rose and her lightsaber-wielding best friend Cy Ob Han? Blacky the master of disguise is back, full of attitude and smelly as ever.
