User blog comment:Bionicleboy3000/Sonic CD - How did Amy get on Little Planet?/@comment-4220590-20120316104645

It is said that Amy predicted that she would meet Sonic with her cards. And knowing her, she would want that to happend, so she headed to where she would meet sonic, and since she predicted her meeting with him, it stands to reason that she would know where it was. So logically, she would go in advance of sonic to the little planet and go to it (possibly by the large chain) in order to wait for Sonic on this planet until he came by. And the rest is history.
