Flipside Pit of 100 Trials

The Flipside Pit of 100 Trials is a location that appears in Super Paper Mario. 
==History==
It is one of the two Pit of 100 Trials located in the game with the other being the Flopside Pit of 100 Trials. The trials are simple - clear all 100 rooms without fail. If the player gets a game over while in the trials, the player will have to start them over. However, any of the card the player has collected from the chests in the trails will remain in their inventory, meaning they cannot obtain them again. The player is allowed to bring any item into the trials, as well as being able to use any character or Pixl. Mario can also flip to 3D, however, it doesn't matter much because the bricks are 2D and Mario will fall right down as soon as he flips to 3D.
Upon entering the Flipside Pit of 100 Trials, the player is put into a room with one or many enemies. One of them will contain the key, which is completely random. As soon as the player gets the key, there is a door in the room with a lock on it. The player cannot go through the door until they've grabbed the key. Also, each room has a timer of 5 minutes. If the player does not complete the room in the time limit, the player will fail. This is unlikely, considering how much time the player has to take out a few enemies. Each room has light shadows of other places the blocks, pipes, and doors could be, possibly a reference to the style of the Game and Watch, which kept all frames on screen. In the background of each room, it shows a pure heart and where Mario got it. It changes every 25 rooms. There is unique music for the trials, and it plays until Floor 100.
==Rooms and Enemies==
The rooms and the enemies in them are fairly easy at first, but the difficulty ramps up the farther you get.
Room 1: The background currently shows a drawing of Flipside along Flopside and the pure heart Mario got there. The only enemy here are Squiglets. There are five of them in the room.
Room 2: The same as room 1, but there are Goombas instead.
Room 3: Also like Room 1, but now there are Squigs as well as Squiglets.
Room 4: It has 5 Boing-Oings in it.
Room 5: Very similar to Room 2, but there are Gloombas as well. There are also more enemies altogether.
Room 6: There are four Cherbils in here.
Room 7: Just like Room 3, but instead of Squiglets there are now Boing-Oings.
Room 8: Just Room 3 but with more Squiglets and Squigs.
Room 9: Two Poision Cherbils appear along with some Gloombas. 
Room 10: Contains a chest with a Tippi card in it. After grabbing the card, you can either leave through the pipe on the left, or keep going through the door on the right. Exiting the pipe resets your progress each time, meaning once you leave, you have to start back at Room 1 again. Each room ending in 0 (excluding 100) is like this, the only difference being the card. If you skip the card on any of the floors, it will stay there until you try it again and take it.
