Bowser Jr.'s Lair

Bowser Jr.'s Lair is the fifth level of the Lava Pit in Mario + Rabbids Kingdom Battle. As the name implies, the stage appears to take place in Bowser Jr.'s bedroom as it features a bed themed after him, toys, and jigsaw puzzle-themed flooring resembling those found in a playroom. Completing this level unlocks Yoshi as a playable character.

Layout
The first part of the level features a plus-shaped arena with four Lava Bucklers evenly split to the left and right of Mario and co., along with one Lava Supporter in the middle.

The second part of the level features Bowser Jr., specifically Mecha Jr., as a midboss. It features the exact same arena as the first, except Mecha Jr. is now in the middle, with two supporting Lava Valkyries. In this battle, the enemies move before the heroes' first turn.
