- Route: Inspect the branching roads after each fortress clears its lock. Decide whether to tackle a puzzle course or a platform course based on your current form.
- Bring: Protect the Leaf while setting up 6-5. Pick a clear stretch before collecting the shell, and avoid releasing the run button accidentally while carrying it.
- Don’t miss: If 6-5 keeps returning you to the cave, look upward: the normal pipes form a loop. The exit requires reaching the high opening, not finding a fourth ground-level pipe.
Boss: Lemmy Koopa
