Paper Mario: the Origami Kingis part platformer, part collectathon, and part open-world game that brings them all together with a unique papery look. There are tons ofhidden objects in the newestPaper Mario, keeping players scouring the levels for collectibles. The Graffiti Underground is a fairly short part of the game, but it has several hidden treasures for players to pick up.
The Graffiti Underground
The Graffiti Underground is the sewers that connect Toad Town and Peach’s Castle. Along with all theToad Town collectibles, players will have to find a hook to open the sewer grate in Toad Town. These tunnels will have two toads, one collectible treasure, two question mark blocks, and five not-bottomless holes.

Not-Bottomless Holes
Not-bottomless holes are holes players can fix with confetti. A holdover from Color Splash, the confetti system is one of the things thatcould be improved in thePaper Mario: the Origami King. However, players that want to complete the game 100% will need to fill all these holes in.
