Mole Patrol is the fourth level in Cave. It is the second rocket barrel level in the world and contains many mole guards. Eventually Donkey Kong and Diddy Kong will reach a mine cart track, in which the Mole Train will be riding on. Throughout the course of the level, it will send mole guards attached to balloons out. These mole menaces will try to chop you with their pickaxes but you can pop their balloons by flying through them.
