Guide your intrepid Jogger across the four-lane motor-way and across the river and finally through a gap in the fence.
Your Jogger might dodge the lorries and cars on both sides of the motor-way but can he hop from croc to log across the river?
The more Joggers you get home the more motor-way traffic there is and the fewer crocs and logs.
You only have a fixed time to get your Joggers home.
