User blog comment:Bionicleboy3000/Sonic CD - How did Amy get on Little Planet?/@comment-3544938-20120316231218/@comment-4018912-20120317125225

Hmm... That theory does seem to work. However, it can be said that the story behind it clashes with itself; the manual states Amy followed Sonic to see the Little Planet, only to be kidnapped by Metal Sonic with Sonic in hot pursuit, while the game itself displays Amy waiting for Sonic in Palmtree Panic, only to be nabbed in Collision Chaos. When you get down to it; it's kinda like the "good ending/bad ending" deal. So, yeah, I'm going with this theory.
