1. Head to the cliff, where Chris and Martin Kratt will be asking for help.
2. Locate a nearby path called "The Outback Trail." This is a path that winds down the side of the cliff and leads to a cave at the bottom.
3. Follow the trail by tapping on the arrows that appear on the screen. You'll need to be careful as you navigate the path, as there will be obstacles such as rocks and logs in your way.
4. Once you reach the bottom of the path, you'll find yourself in a cave. In the cave, you'll need to find a special crystal.
5. Once you find the crystal, tap on it to collect it. This will cause a bridge to form that will allow you to cross the river and continue your journey in the Australian outback.
