Boulder



Boulders are large rocks found throughout various Mario games, which usually serve as obstacles.

Super Mario World
Boulders first appear in Super Mario World, where they are dug up by Diggin' Chucks.

Super Mario Land 2: 6 Golden Coins
In Super Mario Land 2: 6 Golden Coins, they are dug up by Gorontos, similar to the Diggin' Chucks.

Super Mario 64 / Super Mario 64 DS
They also appear in Super Mario 64 in Hazy Maze Cave. In one room, boulders endlessly roll down a slope and into a bottomless pit. If Mario attempts to climb the slope, the boulders will deliberately try to home in on him, although they can be dodged. The level's sixth Power Star is entitled "Watch for Falling Rocks," and is located near the Boulders. In Super Mario 64 DS, Wario must instead punch several boulders, (or ram them upon growing with a Super Mushroom) to receive the Power Star.

Super Mario Galaxy
In Super Mario Galaxy, they roll around in various patterns, and if Mario touches them, he will be knocked down and lose one wedge of his Health Meter. They are semi-common obstacles that appear in several galaxies, including the Good Egg Galaxy and the Honeyhive Galaxy. They can be destroyed if Mario spins their weak spot, a circular red area. They can also be destroyed if Rainbow Mario collides with them, a Stretch Plant is knocked into them, or if Player 2 uses a second Star Cursor to hold one in place, allowing a second one to collide with it, which will destroy both boulders, leaving behind a large number of Star Bits.

Super Mario Galaxy 2
In Super Mario Galaxy 2, Boulders reappear in the Boulder Bowl Galaxy, a galaxy which is appropriately centered around Boulders, as well as the Rock Mushroom. This time, the boulders can also be destroyed by Rock Mario. The boss of this galaxy, Rollodillo, attacks in the same way as a Boulder, and can only be defeated by using Rock Mario. Sorbetti, the boss of the Freezy Flake Galaxy, also uses a similar strategy during the boss battle.

New Super Mario Bros. 2
Boulders make their next sidescroller appearance in New Super Mario Bros. 2. They appear in World 3-5, which is an underwater level. They are common obstacles here but they are also necessary to obtain several Star Coins as they are enclosed in blocks that cannot be broken by Mario.

Donkey Kong 64
In Donkey Kong 64, Boulders appear as stationary obstacles, often appearing on various pads, which require them to be moved before the pads could be used. However, only Chunky Kong can lift them. Boulders also serve as weights, and are sometimes needed to keep various switches pressed down. In this game, they are dark green in color.

Mario Kart 64
Boulders make their first Mario Kart appearance in Mario Kart 64, where they appear as obstacles in Choco Mountain.

Mario Kart: Double Dash!!
Boulders return in Mario Kart: Double Dash!! as obstacles in DK Mountain.

Mario Kart DS
In Mario Kart DS, Boulders appear again in Choco Mountain, which is a retro course in this game. Large pinballs similar to boulders appear in Waluigi Pinball.

Mario Kart Wii
Boulders reappear once more in Mario Kart Wii in DK Mountain, which appears as a retro course.

Mario Kart 7
In Mario Kart 7, Boulders make yet another appearance as obstacles in Rock Rock Mountain and Maka Wuhu towards the end of the track.

Mario Kart 8 / Mario Kart 8 Deluxe
Boulders appear in Mario Kart 8 and its remake as an obstacle in Bowser's Castle. They resemble their Super Mario Galaxy counterparts in texture, but without the red jeweled side.

Trivia

 * During the first part of the final Bowser battle in Super Mario Galaxy, one of Bowser's attacks involves surrounding himself with rock fragments and rolling around the planet much like a Boulder in an attempt to squash Mario. Bowser's head sticks out of the rock in the same area where the red spot would be on an actual Boulder. Mario must spin Bowser's head to break him out of his rock shell.
 * In Super Mario Galaxy 2, the Rock Mushroom is introduced for the first time. When collected, this power-up will allow Mario to transform into a round Boulder-like object and roll into obstacles and enemies, much like Bowser did in Super Mario Galaxy's final battle. Mario's head sticks out of the rock where the red spot would normally be on a regular boulder.
