List of ? Blocks in Paper Mario: The Origami King

A ? Block as a Collectible Treasure.

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

—Musée Champignon, Paper Mario: The Origami King

In Paper Mario: The Origami King, Mario can find ? Blocks 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. Opening all ? Blocks in a given area will show a message informing the player of their success. This page lists the locations of all 368^* ? Blocks, including pictures and information on their contents.

NOTES:

• Only 5 of the 172 ? Blocks found on ? Island are required to satisfy game completion. Thus a total of 201 ? Blocks contribute to the ? Block Head Trophy.^*
• Some ? Blocks are found in areas that are inaccessible until returning later; these entries are highlighted in beige.
• Hidden Blocks will be marked with a Hidden Block Alert icon.
• Locations absent from the list contain no ? Blocks, specifically: Eddy River, Big Sho' Theater, Sweetpaper Valley, Scorching Sandpaper East, West and Far East, The Great Sea, Mushroom Island, Scuffle Island, Diamond Island, and Hotfoot Crater.
