I'm on Chapter 5: Battle for Angel Island. I'm at the part just after Sonic and Knuckles take over some airship. I'm trying to get Tails and his group over to an area at the very southeastern-most part of the map, but I can't figure out how to get up there. I've already completed the puzzle that allows you to go up an escalator, but I can't seem to reach my destination from that point. Thanks for any help.
