Where is Tails when you need him?
Sonic Frontiers stage 1-7is one of many early game stages you could find among the Kronos Islands.
However, it’s seemingly inaccessible - with no rails or platforms leading over to the island.
To reach stage 1-7,you have to find a puzzle switch on the cliffs to the east.
It’ll have three poles nearby, which you must interact with first, creating a tether between them.
Once there, you have another of these puzzles.
This one is easier - it’s just the two poles to connect.
Ride back and across, and you might now access stage 1-7.
Best of luck getting all the keys from the stage!
