In the background of certain levels, you can spot Mario's brother Luigi, who can be peeled off the level by Paperizing. If you peel him off in all 5 locations, he'll appear during the credits sequence. In addition, each individual peeling will unlock a rather amusing newspaper article in the leftmost house in Decalburg's Residential Area.

Wiggler Diary Entries
While going through World 3, Wiggler's segments will be separated, and you will have to find all 4 to access the boss. However, after you "subdue" a segment, it will follow you anywhere you go in World 3, and if you take it to specific places, it will inspire the segment to write a new page for Wiggler's Diary. Note that it doesn't really matter which segment you take where. Also, be warned that these are the ONLY permanently missable things in the game, so be sure you have all five before returning the fourth segment to Wiggler.
Unlockable How to Unlock Wiggler Diary Entry World 3-6: Lead a segment to the overlook to the left of the shop. Wiggler Diary Entry World 3-8: Lead a segment to the poisoned hot springs Wiggler Diary Entry World 3-2: Lead a segment to the dandelion in the area before the Comet Piece, then walk through it to make the puffs scatter. Wiggler Diary Entry World 3-10: Replay the game show while the segment watches. You can skip the bonus round this time. Wiggler Diary Entry Surfshine Harbor: This entry is obtained automatically. You literally cannot miss it.
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.

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.

Megaflash Sticker Locations
Megaflash Stickers are the rarest and most powerful battle stickers in the game, but each one will only ever appear in one set location, (except the Megaflash Hurlhammer, which appears in two) and some can be very tricky to find. However, once you know where to find one, you can get as many as you want, so it helps to know where they all are.
Item Location Megaflash Baahammer World 5-4: On the third floor, through a warp pipe hidden to the right of the moving platforms in the main room. Megaflash Burnhammer World 5-5: In the first area, in a secret room behind a rock near the entrance to the second area.
