—Bouldergeist,Super Mario Manga Mania, page 110

Bouldergeist is a boss inSuper Mario Galaxy and itsNintendo Switchport. Bouldergeist is essentially a huge column of rocks roughly shaped into a face, and its insides are made up of shadows. However, its true form is revealed when its rock armor has been destroyed, revealing a face with yellow eyes and a red glowing tongue or uvula hanging from the bottom. Its eyes and body color are extremely similar to those of theBomb Boos it spawns, though it is not indicated if they are actually related. In its rock form, it also has two enormous stone hands which are used in the second half of the battle. Bouldergeist's attacks include tossing rocks atMario, summoning lines of stalagmites from the floor, and in the second half of the battle, slamming its hands on the ground and punching at Mario. It is fought in a plain circular arena. Its name is a portmanteau of "boulder" and "poltergeist." It is the boss of theGhostly Galaxy. Bouldergeist returns inSuper Mario Galaxy 2 as the fourth out of fiveSuper Mario Galaxy bosses encountered in theBoss Blitz Galaxy, using the same tactics as in the first game. Bouldergeist shares its battle music withKingfin.

Battle[edit]

This battle practices Mario's use of theBomb Boo. To get Bomb Boos, Mario must dodge the black rocks that the Bouldergeist throws at him. Once they hit the ground, they turn into Bomb Boos. Each hit gradually causes Bouldergeist to lose a bit of its stone layer. Three hits completely destroy the entire stone layer surrounding Bouldergeist's real form. Once this happens, Mario has to spin a Bomb Boo at the shadow's red weak point to inflict more damage on Bouldergeist. However, the fight is not over, as Bouldergeist regains its old stone layer, and reveals its large rock hands. Bouldergeist then has a greater variety of attacks, as well as a larger form of protection. Mario can, however, destroy the hands the same way, but they regenerate after a short time, so Mario has to damage Bouldergeist before the hands reappear again. Mario must once again swing three Bomb Boos into it, and then swing one final Bomb Boo into its shadow form to defeat the Bouldergeist and claim itsPower Star (aLaunch Star inSuper Mario Galaxy 2). Also, Bouldergeist may shoot golden rocks which reveal acoin. However, it only shoots up to a maximum of 20 coins.

Bouldergeist's attacks consist of a boulder throwing attack that Mario can only run from, and summoning a row of stone spikes out of the ground, indicated by dark shadows appearing where the spikes will be. The spikes do not harm Mario after they are out of the ground and can be broken with aspin attack. After the boss forms its hands, it has new attacks in addition to the old ones, which change depending on Mario's distance. If Mario is far enough, Bouldergeist draws back its fist, after which it will try and punch Mario. Bouldergeist cannot change directions once it starts the attack so it is easily avoided and used to destroy any stone spikes. If Mario is close enough, Bouldergeist holds its hands over the surface of the arena, after which it uses a slap attack that crushes Mario if not dodged, though it does not cause instant death and only causes him to lose one health point. This is the only instance in the game in which Mario can get crushed without instantly dying. Also, Bouldergeist's stone spike attack forms two rows of spikes that Mario has to avoid. Bouldergeist's inner form is too weak to attack Mario. It can only flee and summon Bomb Boos.

Later, Mario must defeat Bouldergeist with one wedge of health under theDaredevil Comet to claim its second star. Bouldergeist no longer throws golden rocks in this battle.

Bouldergeist has unused animations for popping into and out of the ground, and when it does this its true form appears with a somewhat early design.
