Quarry Stage

Quarry Stage (採石所ステージ) and Underground Stage (地底ステージ) are Tunnel Rhino's stages in Mega Man X3 and Mega Man Xtreme 2, respectively.

Mega Man X3
The Quarry Stage begins outdoors before descending into the mine. It then becomes a vertical climb, avoiding machines that drop mud which slows X down. Next is another climb with falling and rolling boulders this time, followed by a sub-boss fight with Hell Crusher. After another climbing segment full of more enemies than ever, Tunnel Rhino's boss arena is reached.

Mega Man Xtreme 2
The Underground Stage appears on Laguz Island as part of Zero Mission. Compared to the other levels taken from Mega Man X3, the Underground Stage is more similar to its X3 counterpart. It begins outdoors before descending below ground, where there are rolling boulders and pits. However, there is also a Rabbit Ride Armor segment, and later a section where magma periodically floods the lower half of the stage and must be avoided.
