Lava Pit (Mario + Rabbids Kingdom Battle)

The Lava Pits is the forth and final world in Mario + Rabbids Kingdom Battle. Located to the west of Spooky Trails, this volcanic world features many lava pools, mine cart tracks, a factory producing mechas, and Bowser's Castle.

Overview
Mario and his friends land in this world while chasing after Bowser Jr. and Spawny and also trying to stop the vortex. After coming out of a mine, Mario and his friends must then fend off against Mecha Jr. and free Spawny. Afterwards, Yoshi will then join them.

As the team travels further through the area, they will then encounter the physical Megabug, which will capture Spawny right away and spawns Bwario, Bwaluigi, and the Lava Queen. Once those three are defeated, the team will then discover that the Megabug has merged with Bowser, becoming MegaDragonBowser. Once the team defeats MegaDragonBowser, the Megabug is then taken down, and peace is restored to the Mushroom Kingdom.
