- Route: Use the connected branches to collect supplies on the way to the second fortress and castle. Compare the map’s available paths before spending a Cloud.
- Bring: A Leaf helps correct a long jump’s landing. On a large block, stop near the center and inspect the next platform instead of running off the edge with leftover momentum.
- Don’t miss: 4-6 is the world’s signature scale-changing course. Use its doors deliberately rather than treating every door as a one-way shortcut to the exit.
Boss: Iggy Koopa
Iggy moves quickly and fires frequent wand shots in an uneven arena. Aim for a clean landing on his head, then reset your position for the next vulnerable phase. Three stomps win.
4-Airship: Iggy’s slow-scrolling airship splits into two routes, the lower one lined with flame-spewing Rocket Engines.
