Snail Bob being literally cut away from his bearded elderly grandfather while ice-fishing and finding his way across the oceans back into the warm but dangerous jungle. Snail Bob is an ambitious little fella and is always wanting to move unless you put him back in his shell by clicking on him, or tapping the [SPACEBAR].
You can also turn him around and speed him up, either by using the number buttons or clicking on the icon in the corner. It's your job to keep Snail Bob moving the right way, or stopping him to wait for the disasters to pass. Your other job is to push buttons, switch levers, chase away hungry creatures and much more by using clicking to interact with them. Otherwise it's just one slip that ends Snail Bob's life and that is no way to end a vacation.
