In the early stages of New Super Mario Bros. U, players are introduced to the bright and welcoming region known as Acorn Plains. While the world may seem straightforward at first glance, many fans of the Mario series know that Nintendo loves to include secrets for curious players to discover. Among these secrets is the elusive secret level in Acorn Plains, a hidden path that often goes unnoticed by casual players. Unlocking this level is not just about bragging rights it offers a chance to explore more content, collect extra items, and possibly access alternative routes that lead through the game in unexpected ways.
Where Acorn Plains Fits in the Game
The First World of the Adventure
Acorn Plains is the very first world that players explore in New Super Mario Bros. U. As a typical grassland region, it introduces the player to the core gameplay mechanics. With rolling hills, Goombas, Koopa Troopas, and the debut of the Flying Squirrel power-up, it serves as the perfect tutorial zone. However, what makes it particularly interesting is that even in this beginner-friendly region, Nintendo has hidden a secret level that rewards players who are willing to look beyond the obvious path.
Unlocking the Secret Level in Acorn Plains
Where to Start Looking
The key to finding the secret level lies within the standard level titledAcorn Plains-2: Tilted Tunnel. Unlike other levels, Tilted Tunnel includes an alternate exit that leads to the hidden course. This level already stands out due to its underground setting and use of slanted platforms, but the hidden exit is placed in such a way that players can easily overlook it if they’re not paying close attention.
How to Access the Hidden Exit
To reach the secret level, follow these steps while playing through Acorn Plains-2:
- Make sure to grab a Fire Flower or Flying Squirrel Suit early in the level, as these can help clear enemies and reach tricky areas.
- Progress through the stage until you find a red pipe toward the end this is not the normal exit.
- Instead of taking the normal exit, search for a hidden pipe on an upper ledge that can be accessed with some careful jumping or the help of the Flying Squirrel Suit.
- Enter this pipe, and you’ll be transported to a hidden area that leads to the alternate flagpole the secret exit.
After completing the level through this secret exit, the world map will change, revealing a new path that branches off from the main route. This will unlock the secret level in Acorn Plains, known asAcorn Plains-A: Blooper’s Secret Lair.
Exploring Blooper’s Secret Lair
An Underwater Challenge
Blooper’s Secret Lair breaks away from the traditional terrain of Acorn Plains by taking players deep underwater. As the name suggests, Bloopers those pesky squid enemies fill the screen. This level offers a noticeable jump in difficulty compared to earlier levels, particularly because of the water-based controls and enemy density.
What Makes It Unique
- Underwater setting: Controls are floaty and require more precise movement to avoid enemies and reach coins.
- Star Coins: Like every level, there are three Star Coins to collect, and these are cleverly hidden behind breakable blocks or in narrow corridors guarded by Bloopers.
- Power-Ups: The Ice Flower is particularly helpful here since it can freeze Bloopers and make navigation much easier.
Tips for Beating the Secret Level
Move Carefully and Stay Alert
Underwater levels can be disorienting, especially when enemies swarm from all directions. Keeping your movements slow and calculated is essential. Try not to rush forward without checking your surroundings. Bloopers tend to follow Mario’s movement, so baiting them into safer areas can help you navigate tight spaces.
Power-Up Strategy
If you can enter Blooper’s Secret Lair with an Ice Flower already equipped, it gives you a strong advantage. Not only can you freeze Bloopers to avoid contact, but you can also create temporary platforms in rare cases. Alternatively, using a Fire Flower works too, though it’s less effective underwater compared to the Ice Flower.
Collecting the Star Coins
Each Star Coin requires some extra effort to collect:
- First Star Coin: Found early in the level behind a row of Bloopers. It’s guarded, but accessible if you time your movement correctly.
- Second Star Coin: Hidden inside a breakable wall. You’ll need a Koopa shell or Fire Flower to break through the blocks.
- Third Star Coin: Near the end of the level, positioned above the exit pipe. It requires tight swimming and timing to grab without taking damage.
Rewards for Unlocking the Secret Level
Alternate World Map Path
One of the major incentives to find this secret exit is the ability to access a shortcut in the overworld. After completing Blooper’s Secret Lair, the path bypasses several levels and can lead directly to the next major area or even an item house, depending on your route.
Additional Items and Bonuses
Beyond the joy of discovery, the secret level gives access to bonus item houses, 1-Up opportunities, and often leads to richer exploration opportunities in the game. It adds replay value and encourages players to revisit earlier levels to find all possible secrets.
