New Super Mario Bros. Wii: World 4 Warp Cannon Clarification

No Warp Cannon in World 4

If you're hunting for a warp cannon in World 4 of New Super Mario Bros. Wii, you'll come up empty-handed. Warp cannons—which blast you to later worlds—only exist in Worlds 1, 2, 3, 5, 6, and 7.

What World 4-2 Actually Offers

World 4-2 does contain a secret: a hidden pipe located in the top-left area behind a block. This pipe leads directly to the World 4 Castle, letting you skip a portion of the level—but it's not a warp cannon and won't transport you to a different world.

Double-Check Your Goals

• Confirm which world and level you're currently in.
• Verify you're not thinking of a different Mario title with different warp mechanics.
• If you're trying to skip ahead, focus on the worlds that actually contain warp cannons.
