How do you make a shadow chao

To make a Shadow Chao you need to keep it normal and keep giving it green chaos drives.(Normal means it is not hero or dark)It will grow spikes so it will look a little like shadow.When it has its spikes pet it with shadow only and it will be a dark Chao with green quills,green feet,and green hands.It takes 2 hours to evolve so be patient!After it evolves give it green chaos drives constantly.Its quills,hands,and feet will be red and it will look like shadow!
