Paper Mario: The Thousand-Year Door/Star Pieces

Like in the previous game, the Star Pieces in Paper Mario: The Thousand-Year Door are mainly found through flippable panels, in hidden areas, or by completing side-quests. The panels can be flipped by Spin Jumping (possible after Mario finds the Super Boots in Chapter 2) near them. Mario can also find panels by swinging his Hammer against the ground. There are 100 Star Pieces total. Mrs. Mowz is capable of telling Mario if there is one in the area with her field ability, and Merlee in Rogueport Sewers can give Mario clues as to where they are. A character named Dazzle in Rogueport Sewers trades Badges for Star Pieces.
