Can you please answer these? 1.How long does it take chao to get older? 2.How do you get the other gardens?What are they? 3.What is the Mystic melody?How do you get it? Thanks!
1. About 3-5 hours of in-garden time for one chao "year".
2. You unlock the Hero and Dark gardens the first time you evolve a chao into a Hero or Dark type.
3. It's an upgrade that's used to activate the shrines within the levels and is often needed for the third mission. Each character's Mystic Melody is hidden within one of their levels. How to get it for each character is given in the games section.
