In Grand Metropolis Act 1, Team Rose's objective is to find 10 Lost Chao. Start by using Amy to quickly navigate the initial sections. As you progress, keep an ear out for the distinct 'chao' sound effect, which indicates a Lost Chao is nearby. Many Chao are hidden on high ledges or behind breakable objects.
Switch to Cream (Fly formation) frequently to explore vertical areas. Her flight is crucial for reaching platforms that Amy cannot. Look for glowing blue platforms that Cream can lift; these often reveal hidden Chao or pathways. Big (Power formation) will be needed to smash through metal crates or large blocks that might conceal Chao. Don't rush through the stage; take your time to thoroughly explore every branching path and elevated area. Some Chao are cleverly hidden, requiring you to backtrack slightly or take an unconventional route. Once all 10 Chao are found, the goal ring will activate.
