Once Augie Doggie has reappeared on the screen, you will have to start walking to the right and crouch down over a piece of cheese to collect it for 125 points; once you have done so, you will have to crouch down over a beetle while pressing the joystick's button, to catch him for 175 points. You will then have to jump over a ball that is rolling back and forth, walk under a bat that is flying up and down above you, and crouch down over another beetle while pressing the joystick's button to catch him for 175 more points - and once you have done so you will have to walk under another bat that is flying up and down above you, and crouch down over another piece of cheese to collect it for 125 more points. You'll then have to jump over another ball that's rolling back and forth and crouch down over a third beetle while pressing the joystick's button to catch him for 175 more points; once you've done so, you shall have to walk under a third bat that's flying up and down above you and crouch down over a fourth beetle while pushing the joystick's button to catch him for 175 more points. A cat will then fly into view from the right side of the screen on a paper aeroplane while dropping bombs on you, so you will have to stand in a place where you know his bombs will not land on you - and once he has passed, you will have to crouch down over a third piece of cheese to collect it for 125 more points. You will then have to walk under a fourth bat that is flying up and down above you, and crouch down over Doggie Daddy's pipe to collect it for 50 points; once you have done so, you shall have to crouch down over a fifth beetle while pressing the joystick's button to catch him for 175 more points. You then have to retrace your steps back to the start of the stage (avoiding all the hazards), and walk off the left side of the screen onto the house's balcony to free the stage's first five beetles (which shall fall to the ground from the balcony and make room for the sixth to tenth ones).
Once Augie Doggie has reappeared on the first floor you shall have to retrace your steps back to the right side of the fourth bat as a second cat flies into view from the right side of the screen on a paper aeroplane while dropping bombs on you, so you will again have to stand in a place where you know his bombs shall not land on you; once he has passed, you shall have to crouch down over a fourth piece of cheese to collect it for 125 more points. You will then have to crouch down over a sixth beetle while pressing the joystick's button to catch him for 175 more points - and once you have done so, you will have to jump over a third ball that is rolling back and forth, walk under a fifth bat that is flying up and down above you and crouch down over a fifth piece of cheese to collect it for 125 more points. You shall now have to walk under a boomerang that's flying back and forth above you, and crouch down over a seventh beetle while pressing the joystick's button to catch him for 175 more points; once you have done so you will have to crouch down over a sixth piece of cheese to collect it for 125 more points. You now have to jump over a fourth ball that is rolling back and forth, walk under a fifth bat that is flying up and down above you, then crouch down over an eighth beetle while pressing the joystick's button to catch him for 175 more points - and once you've done so you have to jump over a fifth ball that is rolling back and forth and crouch down over a seventh piece of cheese to collect it for 125 more points. You'll then have to walk under a sixth bat that is flying up and down above you, and crouch down over a ninth beetle while pressing the joystick's button to catch him for 175 more points; once you've done this, you'll have to jump over a sixth ball that is rolling back and forth, and crouch down over a tenth beetle while pressing the joystick's button to catch him for 175 more points. You will then have to crouch down over an eighth piece of cheese to collect it for 125 more points - and once you have done so, a third cat shall fly into view from the right side of the screen on a paper aeroplane so you will once again have to stand in a place where you know the bombs will not land on you. Once he's passed, you will again have to retrace your steps back to the start of the stage (again avoiding all the hazards), and walk off the left side of the screen to free the stage's next five beetles; once you've done so, you will receive a "Completion Bonus" of 3000 points, along with the "Cheese Bonus" of 100 points for each piece you had collected, and the "Time Bonus" of 10 points for each second you have remaining. Augie Doggie shall now proceed to the fourth stage, "The Attic" (in which the pests are, again, mice).
