Musée Champignon

Musée Champignon (French for "Mushroom Museum") is a museum in Paper Mario: The Origami King. It is a large, white building in Toad Town, next to the Battle Lab. The owner of the museum is a yellow Toad with glasses, who stays at the front desk and tells Mario if any new pieces have been added. Mario can also collect any trophies he has earned from the Toad. Musée Champignon is similar to the Sticker Museum from Paper Mario: Sticker Star and the Prisma Museum from Paper Mario: Color Splash.

The museum's lobby contains four exhibits: an ancient submarine called the Super Marino (which is replaced with a 1/24 scale model after its owner is rescued and arrives to retrieve it), a gray Warp Pipe that leads to a fast-travel hub to other areas, and fish prints of the Cheep Cheep and Blooper, if Mario has caught any. The Art Gallery is located to the west, the Sound Gallery is to the east, and the Origami Toad Gallery, Treasure Gallery, and Origami Character Gallery are north of the entrance. If Mario has any new pieces in a gallery, the light above the door is illuminated.

After Mario has earned every trophy available (completing all of the museum's collections in the process), the curator states he is able to double the admission price, although Mario's can still enter at his leisure, and Toads can be seen visiting the lobby and galleries.

Art Gallery
The Art Gallery features a total of 150 pieces of artwork, which all require a total of 416 Toad Points to be unlocked.

Origami Toad Gallery
Some origami Toads appear in multiple sections under different numbers (indicated in gray), though they have the same description. There are 54 different origami Toad designs.

Treasure Gallery
There are 120 Collectible Treasures and 15 trophies in total to collect.

Origami Character Gallery
The Origami Character Gallery is organized into nine categories: each of the five streamers and "Origami Castle" for the enemies, "Vellumental", "King Olly - Vellumental Forms", and "Special". In order to unlock an enemy, with the exception of the Thwomp and Fuzzy, the player has to defeat it in battle, as defeating it in the overworld with high HP does not count. Some enemies are present more than once in this gallery, though they have same descriptions in every section (with the exception of the Ninjis, which have a different variant that hold tree branches). An enemy is unlocked in all sections regardless of where the player first fought it.

Enemies
The colored columns indicate the section in which an enemy appears (R, B, Y, P, and G for the red, blue, yellow, purple, and green streamers respectively, and O for Origami Castle), marked by its number in the corresponding section.

Sound Gallery
The Sound Gallery features a total of 244 songs.

Fish prints
If Mario has caught a Cheep Cheep or Blooper at any of the fishing spots, a fish print of his largest catch for each fish is hung on the wall in the lobby (the Cheep Cheep on the left and the Blooper on the right). Obtaining the largest fish prints (after catching the Legendary Cheep Cheep and Legendary Blooper) unlocks the Fish Finder trophy.
