Super Block

Super Blocks are blocks that contain a spinning blue disk in Paper Mario. Similar to Merlon's power in Paper Mario: The Thousand-Year Door, the Super Block upgrades Mario's partners. There are 16 blocks scattered all across the Mushroom Kingdom, with each of the 8 partners being able to upgrade twice. The fortune teller Merluvlee can tell where the Super Blocks are.

Each of Mario's partners can be upgraded twice: the first time to a Super Rank and the second time to an Ultra Rank after Mario receives the Ultra Stone from Raphael the Raven in Chapter 5. After Mario receives the Ultra Stone, he can choose to Ultra Rank a partner even if all partners aren't at Super Rank yet.

Trivia

 * In The Adventures of Super Mario Bros. 3 episode "Super Koopa", Mario refers to a standard Brick Block as a Super Block.
 * In the Virtual Console re-release of Paper Mario, the brightness of the Super Block was changed to avoid the risk of seizures.
