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.
- 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.
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.
- Luigi Location - World 1-6: On the bridge leading to the central tower, look in the backgrond.
- Luigi Location - World 2-5: On the fourth floor of the tower, in a window on the far right end of the second outdoor walkway.
- Luigi Location - World 3-12: On a rock formation sticking out of the ocean in the background that's only visible from the pier.
- Luigi Location - World 4-5: Near the end of the chairlift after the enemies stop coming. You only have so much time, so be quick.
- Luigi Location - World 5-5: In the background to the left of the hot springs.

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.
