How do I get a hero sonic Chao. I gave it a load of greens. I gave another one bunny's. What do I do? And is there a Shiney Blue egg.
There is no Hero Sonic Chao. If your chao is already a Hero, it can't become a Sonic chao on that life because Sonic chao are Neutral/Running/Running, not Hero/Running/Running. And yes, there are shiny blue eggs available in the Black Market.
