Hint: Easy lives:
Get to the second part of the first level. When you see the clowns appear from the giant present walk a short distance until you see the first bench. Do not move from there. Stand there and throw Bat Rangs at the clowns. They will keep respawning. Every time you get 50,000 points you get an extra life. Note: This may take some time.
