Sweetpaper Valley

Sweetpaper Valley is a location in Paper Mario: The Origami King, a small, tranquil valley interlocking the Eddy River and Breezy Tunnel, located in the yellow streamer district. Mario, Olivia, and Bob-omb must travel here after completing the blue streamer district. There is not much to do, but as they try to enter the tunnel, King Olly appears and tries to convince Olivia to join him in overpowering the paper people. When she refuses, he drops a massive boulder on her and leaves. With Olivia trapped, Bob-omb has an epiphany and asks Mario to take him out to sea - a shortcut can be found in Toad Town.

After Bob-omb finds his fuse, the duo travel back to Sweetpaper Valley, where Bob-omb sacrifices himself to blow up the boulder trapping Olivia. When Olivia discovers this, she becomes extremely disheartened and runs off into the tunnel. Mario must head into the tunnel to find Bob-omb's spirit, who encourages Mario to make Olivia laugh. Mario equips the Goomba Mask to cheer Olivia up.

There are no enemies to be found here. There are also no Toads to be rescued, collectible treasures to be found, or ? Blocks to be hit. There are only a few Not-Bottomless Holes in the area, including some on the walls, some in the ground, and one underneath a crate.

Trivia

 * Towards the end of the cutscene when first arriving to Sweetpaper Valley, the camera actually swerves past the boundaries of some rocks for about a second, unintentionally having the player see the rocks with no back polygons, allowing the player to see right through them from the back.
