Don't let Boo stop your progress in World 1-4. Follow this guide to clear the way and keep moving.
"You cannot defeat a Boo — they are invincible. Face them directly to freeze them in place, then carefully route around them while they are stationary. Never turn your back on one in a tight corridor."
Face a Boo directly to stop it in its tracks — it covers its eyes and freezes.
Use their freeze state to reposition yourself safely before moving past.
Never turn your back on a Boo in a narrow corridor — it will close the gap fast.
Plan your route around them before moving — hasty decisions lead to inescapable traps.
Level Context
Bowser's first castle — a fiery, maze-like fortress with lava pits, moving firebars, and a boss fight at the end. The fake Bowser here is actually a Goomba in disguise. Duck under the axe to drop him into the lava.
