The Adventures of Blinky Bill S02 E09 Blinky Bill and the Earthquake

"Following the destruction of their village by loggers, a young koala and his friends help to rebuild anyway they can."

Continuing their camping trip, Blinky's gang slip away to explore a mountain mine. They get trapped after a collapse. As they try to find a way out, a creepy Goanna frightens and chases them through tunnels and down a mine shaft in carts. Once outside the mine and down a river, Blinky's gang are very far and lost from Greenpatch.
