Lost Chao Locations
Locating the Ancient Ruins:
Work through the stage until the area after the floating platforms, G.U.N. Beetles and springs. You will be in an area with red flowers and the third checkpoint ahead of you. If you look to the left you will see the Ancient Ruins on the platform below.
Finding the Lost Chao:
Activate the ruins with the Mystic Melody and some platforms will appear. You need to use the Bounce Bracelet to bounce onto them. At the top, you will find a trail of G.U.N. Beetles that you will need to homing attack to take you right to the Lost Chao.
