Stone block

Stone blocks (also formatted as Stone Blocks) are gray blocks that appear in Paper Mario. Stone blocks appear in various locations, blocking Mario's way. They most abundantly appear in Dry Dry Ruins, as these blocks cannot be pushed, smashed by the regular Hammer, or destroyed by other means. They can be broken only after Mario obtains a Super Hammer from Dry Dry Ruins. Stone blocks sometimes, albeit rarely, contain enemies, such as a Stone Chomp.

In Paper Mario: The Thousand-Year Door, an Ultra Hammer is required to break stone blocks. However, the Ultra Hammer appears late in the game, and it is needed to smash only a handful of stone blocks. Additionally, large stone blocks appear, and they require spinning the Ultra Hammer to destroy.

In Wario Land 4, stone blocks are often used as walls and obstacles. They can be destroyed by any attack, and they occasionally conceal Diamonds or paths.

Wario Land: Shake It! uses stone blocks as its predecessor did. Breaking them is required by some levels' missions.
