Flopside
Flopside is the complete opposite of Flipside from the game Super Paper Mario. It is accessible after Chapter 4. As a complete reverse, even the people are in the reversed place, with reversed personalities. For example, Pook of Flipside loves the sea, while his Flopside counterpart, Puck, prefers the sky. They are both located in the third floor of thier respective towns. It has the same places from Flipside in reverse direction, even including the Pit of 100 Trials. One of the salesmen is called Flamm, a counterpart to Flimm.
More importantly, Flopside's Heart Pillars are all located in the same place as Flipside's. Also, Saffron's counterpart mixes two items instead of simply cooking one.
If Mario flips to 3-D on the second floor of Flopside, he can pay 300 coins to have a warp pipe constructed by Merlee's house that connects to a warp pipe by Merluvlee's house. This creates an easier route between Flipside and Flopside.
