List of ? Blocks in Paper Mario: The Origami King

"You've found—and hit—each and every ? Block in the game. Now tell us...which one was your favorite?"

- Musée Champignon

In Paper Mario: The Origami King, Mario can find &s throughout the different Streamer areas, receiving various rewards when struck open. Typically, Mario can use his hammer or jump into the blocks from below, however some blocks are hidden or folded in the case of Origami Castle. Locating these blocks is made easier after purchasing the Hidden Block Alert from the Fun, Funky, and Functional vendor in Snif City, or by acquiring the Hidden Block Unhider from the Toad Researcher 's Sensor Lab in Picnic Road. This page lists the locations of all 369 ''? Blocks'', including pictures and information on their contents.
