Hint: Easy levels and money:
Go to Pureland. Go to the underground world and get UUE-ray, But Not U-SOAR. Exit the way that you came in. Attach the UE-ray to the Talon. Fly around. If done correctly, the Talon should kill all of the enemies before you even touch them. You will still get the experience and gold.

Hint: Easy money:
In the future after you have got Morph go to Muu, the town where everybody has turned into Waterhags Go to the Inn but do not Morph just yet. Talk to the man at the Inn and fight him. Kill him repeatedly. Each time this is done, he will give you 1200G. If you get hurt, just Morph and stay at the Inn. Then, Morph back and fight him again. He will always be there.

Hint: Hurt characters without losing health:
Climb underneath a bed and press Jump. Your selected character will say "Ouch!!".
