Super Mario Bros. 3 and Super Mario Galaxy reference

During the introduction sequence, you can see Bowser Jr. and the other Koopalings leave after kidnapping Princess Peach and taking off in an airship from Super Mario Bros. 3 and Super Mario Galaxy.

When you enter the airship the background music is the airship song found on Super Mario Galaxy.

Yoshi's Island series reference

After defeating the Koopa Kids once, Kamek casts a spell to make them tougher for the rematch. In Yoshi's Island and Yoshi's Island DS, he also cast spells on those Bosses that made them tougher.

Make mushroom houses appear in multiplayer

To get a mushroom house to appear in multiplayer, you simply need to clear the level when the time has the same 2 end digits next to each other when you touch the flag pole. Examples: 544, 322, 411. Depending on the two end digits, you will make different mushroom houses appear at the start point, as you would in single player when you save a Toad, only the digits are mostly red mushroom houses. Two zeros at the end will get you nothing. When you do this, you hear the original Super Mario Bros. level clear music and see a number of fireworks depending on what the last 2 digits are. 1 firework for 11, 2 for 22, and so on.

Unlockable	How to Unlock
Gold Mushroom House	Touch the flagpole with last 2 time digits as 99.
Green Mushroom House	Touch the flagpole with last 2 time digits as 11 or 22 at the end.
Red Mushroom House	Touch the flagpole with last 2 time digits as 33, 44, 55, 66, 77, or 88.

Head protection

When in front of a small item such as a turtle shell, press 1 and shake the Wiimote while picking it up. Holding it over your head will protect you from falling objects.

Turtle Tipping for 99 Lives

You can use the decades old turtle-on-the-stairs trick from Super Mario Bros. to get 99 lives in New SMB Wii. Go to world 2-3 and, at the end, right before the flag, you'll find a set of steps and a turtle ambling down them. If you time your jump just right you'll continue bouncing on the shell collecting lives until you max out at 99.

Sounds From Beyond the Grave

When you're playing multiplayer and one of the players runs out of lives mid-level, he or she can still contribute to the game from the Great Beyond. Each direction of the D-pad is mapped to a different sound effect. Hold a direction and hit the 1 and 2 buttons to trigger different sounds, including clapping, a horn, kick and snare drums, and of course cowbell. The unfortunate players waiting for the level to end can add a drum line to the music.

Double Ground Pound (Multiplayer)

With at least two human players you can perform a special double ground pound that has the ability to kill all nearby enemies much like a POW block. You'll need to time your ground pound (press JUMP then DOWN) so both players hit precisely at the same moment.

Knock Out Marauding Enemies

On the world map you'll encounter marauding enemies. To avoid these map screen enemies you can activate a star from your item menu.

Mushroom House Bonanza

Beat the game to make all the Mushroom houses in Worlds 1-8 reappear. Collect all the Star Coins and visit every Warp Cannon to make the houses reappear and stay for good.

Save Anywhere

After you beat the game (beat World 8-Bowser's Castle) you'll be able to "hard save" anywhere you'd like. The option replaces the Quick Save option.

Flower Coins

Shake the Wii Remote to spin and jump on any of the small, dancing flowers in the game to make a coin appear.

Stealing Red Mushroom Houses (Multiplayer)

When playing multiplayer you can steal your teamates turn in the Red Mushroom House match game by performing a ground pound on him.

Lose Your Hat Easter Egg

Once you get 99 lives, Mario will lose his hat! When you beat a level with a full 99 count, Mario will appear hat-less on the map screen and in subsequent gameplay. You'll regain your hat once you lose a single life.
