Skyway's secret lies in the ground; a second hidden track that will test your ninja skills.
From the start, launch onto the first ramp. Slowly back up and fall back into the gap you jumped over and you should land safely below on a ramp. Ahead of you lies the dreaded ninja course.
The purpose of this hidden track remains unknown. Nobody has yet to beat it. It is assumed that getting from start to finish may trigger some kind of switch, but it remains unknown for now.
This section is reserved for Confirmation/comments about this investigation. Investigations will remain open until advised by Redlynx that the final solution for each secret is found.
