26+ Graffiti Underground Origami King Pictures. Once you unlock the sewer grate in toad town and drop down, you'll find yourself in a pitch black room, the first in underground graffiti. Please keep in mind, some collectibles can't be obtained the first time you arrive in a level.
One of them has the looks of dripping paint while the other comes without that effect.
We're almost on the trail of the first red streamer. Next to it is graffiti of mario and peach. The first area has a light switch on the right side of the entrance. Check your map, using the + button.
