List of hidden blocks in Paper Mario

Mario revealing a Hidden Block in Shy Guy's Toy Box.

In Paper Mario, Mario can discover Hidden Blocks throughout the Mushroom Kingdom. Like regular ? Blocks, these invisible blocks contain coins, items, and even badges. Mario can reveal them by using Watt's field ability by pressing ; however, Mario can still uncover them himself without her, even before she joins his party. All Hidden Blocks are revealed by jumping at them -- there are no Hidden Blocks on the ground that must be hit with the Hammer. Some Hidden Blocks are too high for Mario to hit with an ordinary jump and thus require the use of the Tornado Jump from the Ultra Boots to reveal them (such as four mandatory ones in Toad Town Tunnels leading to Shiver City). Hidden Blocks will never be found in areas with NPCs; as such, they will not be found in shops or houses. If Mario reveals a block containing an item or badge, then leaves and returns to the area without collecting the contents, the block will become invisible again until he does so. Some invisible blocks are used as stepping stones to reach new places or other items. There are 47 Hidden Blocks in the game. This page lists the location of each Hidden Block, the contents, and how to get to them.

Hidden Block locations

Location	Item	Description	Image
Goomba Village	Repel Gel	In the area immediately east of Jr. Troopa's playground, Mario will find a gray block that can only be broken with the Super or Ultra Hammer. Jumping in the center where the block once was will reveal the Hidden Block. If Mario doesn't have the Super or Ultra Hammer, he can still hit the block by jumping on the Brick Block near it and using Kooper or Bombette while on the Stone Block.
Pleasant Path	Fire Flower	In the area two screens west of the Koopa Bros. Fortress, the Hidden Block is between the two Brick Blocks.
Dry Dry Desert (Area B1)	Thunder Rage	In the area two screens north of Kolorado's camp, the Hidden Block is above the easternmost rock.
Dry Dry Desert (Area G2)	Attack FX C Badge	In the area one screen east and three south from Kolorado's camp, the Hidden Block is above the lone rock.
Dry Dry Desert (Area C5)	Runaway Pay Badge	In the area one screen north and four east from Kolorado's camp, the Hidden Block is in the center of the triangle of trees.
Dry Dry Desert (Area E7)	Life Shroom	In the area one screen north of the oasis, the Hidden Block is above the ? Block on the ground.
Toad Town Tunnels	Super Shroom	In the area one screen east from the entrance, the Hidden Block is in the middle of the gap in the row of blocks.
Toad Town Tunnels	1 Coin each	In the area one screen west of the blue Warp Pipe to Boo's Mansion is a gap between the two high platforms with the Super Block on the western one. There are three Hidden Blocks in this area. Using the blue movable block, Mario should move it to the middle of the left side of the floor grid pattern (where the blue block is), the center, and the middle of the right side and jump from the movable block at those spots to reveal them. Alternatively, Mario can also hit the invisible blocks without using the blue movable block by using the Tornado Jump if he has obtained the Ultra Boots.
Toad Town Tunnels	Maple Syrup	In the area two screens east of where the player obtains the Ultra Boots, near the starting pipe, Mario should jump at the center of the pathway sticking out to reveal the Hidden Block.
Toad Town Tunnels	Stop Watch	In the same area, from the pipe, Mario should follow the central path going east. The Hidden Block is located just before the path splits north and south.
Toad Town Tunnels	Volt Shroom	Also in the same area, near the doorway, the Hidden Block is west of the visible one.
Toad Town Tunnels	Life Shroom	In the next area, the Hidden Block is between the two sets of three blocks. The Ultra Boots are needed to hit the block.
Toad Town Tunnels	1 Coin each	In the area two screens east of the blue Warp Pipe to Yoshi's Village is a gap between two high platforms, with a doorway leading to Shiver City in the east. There are four Hidden Blocks in this area. Starting from standing under the visible ? Block touching the western platform, Mario should move two block lengths from it and Tornado Jump to reveal the first Hidden Block, then continue to use the same method for the next blocks to reveal them all.

Trivia

• Unlike Surprise Boxes in Super Mario RPG: Legend of the Seven Stars and invisible ? Blocks in Mario & Luigi: Superstar Saga which have to be hit twice to collect their items (first time to even reveal them), Hidden Blocks in Paper Mario immediately drop their items as soon as they're hit and revealed.
• In Gusty Gulch, there is a ? Block containing a single Coin inside a small house with no door one screen east of the Windy Mill. Close inspection through the cracks on the top of the house reveals the ? Block is not invisible.
