General Tips for Collecting

Explore Every Nook and Cranny: Many collectibles are hidden off the main path, behind walls, or in seemingly inaccessible areas.
Utilize Character Abilities: Luigi's higher jump, Peach's float, Toad's speed, and Rosalina's spin attack can be crucial for reaching certain items.
Look for Clues: Sparkling areas, suspicious blocks, or unusual enemy placements often hint at hidden items.
Use the Cat Suit: The Cat Suit is invaluable for climbing walls and reaching high platforms where many collectibles reside.
Don't Forget the Timer: Some Green Stars are time-sensitive, requiring quick action.
Revisit Levels: If you miss something, don't fret! You can always replay levels to snag any forgotten items.
