Flopside

Flopside is the mirrored counterpart to Flipside in the game Super Paper Mario. The main features that distinguish Flopside relatively from Flipside is that all buildings, areas, and residents are reversed and that the town is painted in shadowy tones to set off the pastels of Flipside. Flopside contains its own Pit of 100 Trials; the boss of which is Shadoo. The Mirror Mansion serves as a bridge between the two towns.

Because of the reversed nature of Flopside, the residents of the town are the opposite versions of the residents of Flipside, which in turn causes them to have different personalities, or perhaps different preferences. For example, Pook of Flipside loves the sea, while his Flopside counterpart, Puck, prefers the sky. Another example is the cook Dyllis, Saffron's counterpart, who mixes two items instead of simply cooking one.

Flopside was created by both the Tribe of Ancients and the Tribe of Darkness as an antithesis to Flipside. It was first realized that without darkness (as Flipside was a town of light), Flipside would fall into ruin, as light cannot exist without darkness. As a result Flopside was created as a town of darkness to offset Flipside. The two towns are in perfect balance and have been ever since.

As a side note, all the Heart Pillars in Flopside are located in the same spot in relativity to Flipside.

Trivia

 * Though many assume only a select few in Flopside know of Flipside, by the time the player has beaten the game many residents will mention Flipside--one of them in fact moves to Flipside.
 * Flopside's name derives from the second half of flip-flop, flop (as opposed to Flipside deriving from flip).
 * Flopside's music is a distorted variation of the Flipside music.
