Lava Dome

Lava Dome is the fifth floor in Mario vs. Donkey Kong 2: March of the Minis. Volcanoes and a smoke-filled night sky can be seen in the background. The music tracks played on this floor are remixes of the Bowser's Castle theme from Super Mario Bros.; additionally, this floor bears a significant resemblance to worlds concerning Bowser found in various other Mario games.

This floor features fire-based obstacles such as lava, Podoboos, and Fire Bars. Spy Guys are introduced on this floor, while Crash Kongs and Cool Kongs return from previous floors.

The battle with Donkey Kong in Room 5-DK, referred to as Boss Game 5, plays similarly to Boss Game 1 in Room 1-DK. However, instead of dropping barrels and dumbbells, Donkey Kong will slam the ground to drop fireballs from above. After taking a hit, Donkey Kong will drop a large amount of fireballs, as well as a. If a Mini Mario comes in contact with a, it gains a shield that protects it from fireballs and Fire Bars while in the air. However, if the Mini is hit by a fireball while still in the cannon, the shield disappears. If 30 Mini Marios are destroyed, the game is over. After taking 6 hits, Donkey Kong is defeated and flees to Toadstool Castle.

Upon completing Room 5-DK, the Lava Dome construction kit is unlocked for the Construction Zone.

From levels starting with 5-5, Fire Blocks will start appearing across levels. They work like Pink Blocks but when removed, the background starts flashing yellow and the player can place a fireball on a wood platform and burn it to access previously inaccessible areas.
