Heart Pillars are objects that appear on the 2nd floor and around the outskirts of Flipside and Flopside in Super Paper Mario.
Info[]
When a player completes a chapter and receives that particular chapter's Pure Heart, it must be set in a Heart Pillar in order to open a new dimension door leading to the next Pure Heart. Each Heart Pillar is blocked by certain obstacles that may only be overcome with the abilities of a certain hero or pixl obtainable from that chapter.
Location[]
The locations and the obstacles of each Heart Pillar are as follows:
1st: Located at the 2nd floor of Flipside, accessible once the player gains control of Mario for the first time.
2nd: Located at the outskirts of Flipside's ground floor. Merlon's old key is required to open the gate to the outskirts, Mario's 3D ability is required to get on top of the platforms and to go to the outskirts, and Princess Peach's floating ability is required to hop over the long gaps.
3rd: Located at the outskirts of Flipside B1 floor. Boomer is required to blast the blocks covering the pipe down, and Slim AND Mario's 3D ability is required to fit through the small gaps which only can be seen in 3D.
4th: Located at the outskirts of Flipside's first floor. Thudley is required to ground pound the pillars to make the Heart Pillar itself appear.
5th: Located at the 2nd floor of Flopside. Boomer is required to blast a cracked wall blocking the area behind Flipside's ground floor. Fleep is required to gain access to Mirror Hall and therefore, Flopside.
6th: Located at the outskirts of Flipside's ground floor. Mario's 3D ability AND Dottie is required to fit through the small gaps below the blocks (forget about hopping around them, since invisible walls block the way), and Cudge is required to smash the yellow block which blocks the red switch that makes the Heart Pillar appear.
7th: Located at the outskirts of Flopside's B1 floor. Luigi's jump height (his super jump is not needed) is required to hop over the tall wall and reach the pillar. Of course, you CAN use the 3D swapping glitch with Mario for this.
8th: Located at the outskirts of Flopside's 1st floor. The white Pure Heart itself is required to make the pillar appear. (Before that only the slot will be there)
