Golden egg:
There is a gold egg in a little antique store by City Hall. At City Hall there is a tree and under that tree is a white egg with blue spots. Pick up the egg and go to the antique shop. In the shop, take the golden egg off its platform. A security gate will close on the entrance door. Then put the white egg on the golden eggs' platform. Take the golden egg with you to a chao garden. Hold the egg or throw it and a little golden chao will pop out.
