Circle Of Flowers Secret
If you paperize the area around a circle of flippable flowers, you will see a stickable area appear. Stick a sticker and a "?" block will appear. Inside the block will be a more powerful version of the sticker you originally stuck.
Enemy Exhibition Room
Collect all 96 battle stickers.
Enemy Viewing Area
Once you place all of the Battle Stickers in the museum, a new door appears. Pass through it and you'll find that if you pay a single coin, you get to see enemies attacking a cutout of Mario. Various animations will display as those enemies attack.
If you find Luigi five times while playing through the game, he'll appear at the start of the end credits, holding the banner. The locations where you can find Luigi are as follows.
|Drybake Stadium||Near the top of the tower on the outside, in the window.|
|Goomba Fortress||At the second bridge in the middle of the level.|
|Rugged Road||In the spa area.|
|Whitecap Beach||At the very end of the dock you can see him in the distance.|
|Whiteout Valley||Visible as you are going up the ski lift.|
Hidden Song At Game's End
After beating the game (and watching the credits), the screen will shift to the book from the start of the game. The book closes and the light turns off. At this point, just wait about three minutes. A hidden lullaby song will start to play, and will continue to play until you hit a button.

This has the locations of all 16 HP-Up Hearts. Each HP-Up Heart increases Mario's HP by 5.
