Super Paper Mario/Chapter 6: Sammer's Kingdom

Heart Pillar 6
If you meet with Merlon, he'll inform you that the next Heart Pillar resides in Flopside Outskirts. So venture forth to Nolrem's house in Flopside, then go through the nearby gate in 3D. Stay in 3D to continue down the path to Flopside Outskirts where you'll find a large, yellow block. Destroy it with Cudge to reveal a warp pipe.

Now in the basement's first floor, flip to 3D at the sign to discover another path. Use Dottie's shrinking power to walk beneath the structure, then use Cudge to hammer away the large yellow block (visible in 3D), to reveal a red switch. Step on it to make the Heart Pillar appear. Now use the return pipe to quickly get back to the door.

Chapter 6-1: SammerGuy Showdown
Strangely, Sammer's Kingdom looks so asian, but that's beside the point. Head right, Sammer will come up and tell you about a tournament that he has going on. The prize? A very needed pure heart. Guess you have no choice to win, no matter what. Beat every one of King Samson's warriors. A simple strategy is to use either Bowser with Barry (if you have him) or Carrie. You can also use Peach with Cudge, or Mario with Barry or Cudge, but whatever works for you should do you well. When you beat the 20th, they will let you go by without a battle. Hit the Star Block after the 25th warrior.
