- Route: Clear 1-1 and 1-2, then choose whether to visit 1-3 for its secret or head toward the fortress. A normal fortress victory opens the locked shortcut near the start.
- Bring: Keep a Super Leaf for the fortress’s hidden ceiling route. For a first complete playthrough, spend time learning how much runway the P-Meter needs instead of using a rare P-Wing here.
- Don’t miss: Both World 1 whistles can be collected before leaving Grass Land. Collecting them is optional: keep playing normally if you want to see all eight kingdoms.
Boss: Larry Koopa
Larry fires wand shots and retreats into a moving shell after a stomp. Wait until he comes out before aiming the next jump. Three head stomps win the fight.
1-Airship: Larry’s autoscrolling airship bristles with cannons and Bullet Bill launchers, including one that fires two cannonballs at once.
