Secrets:-  episode 1: in episode, in the beginning you know that babe on the faraway platform, well to get her you have to go  through the whole stage. when at the end turn around walk back to that brown astroid and will see a jetpack, on the other side  three lives. now go back to your space ship in the beginning and go to the back thruster and there is another life. go by the sign that says "welcome to uranus" and fly all along there and there is at least 5 or 6 lives there too.

Episode 2: eventually you will see a pear head carrying a newspaper in his hand. Follow him. when he goes to the toilet, blast him away and you will get a gun and extra lives. 

Episode 3: somewhere in this level there will be a big gap between platforms. There should be 2 lives floating in mid air. if you look  closely the stars form steps to a platform full of lives.

Thieving:-  while walking around towns and such you can steal a few zenny's here and there. Give the people a whack with your sword and they will pop out. Usually about 4 to 6 each time. this will even work on dogs and other animals.
