Brother, Where Art Thou?
Brother, Where Art Thou? is the fifth level of Ancient Gardens in Mario + Rabbids Kingdom Battle. Its name is a reference to the film O Brother, Where Art Thou?. Completing this level unlocks Luigi as a playable character.
Before the level begins, Mario hears Luigi's screams, and decides to investigate.
The first part of the level introduces the knowledge of damage bonuses from attacking at a greater height. It has a small pond near the center, with two Garden Ziggies and two Garden Hoppers guarding it. Another Garden Ziggy can be found on higher ground, near a dropoff zone.
The next part of the level features Pirabbid Plant, the first boss of the game. This arena is symmetrical, having two higher platforms on each side. There are also Burn and Push covers found here, and a total of four Garden Ziggies: two beside Pirabbid Plant, and two behind some Push covers on opposing high platforms.
Once Pirabbid Plant is defeated, Luigi joins Mario's team.
"Through the Lawns" can be found straight after the second fight. The player will enter a pipe to their right leading them to several coins and this treasure.
Spike Strike can be found by completing the bonus room. The cannon is up and to the right of the first platform with blocks. If the player hits a green switch, nearby blocks open, leading to the cannon. The bonus room is made up of three walled off areas. The first one (the starting point) has four coins and a pipe, leading to the second, which has coins along with a switch that opens blocks between the first and third areas, allowing the player to grab the last few coins.
Bowser Basher can be found by hitting all the switches, then collecting the eight Red Coins. The green switch is described above, which opens the path to the blue switch, which opens the yellow switch, which opens a cannon to the red switch. Once all of those are pressed, a platform appears near the Bonus Cannon, which has the Red Ring. The chest appears in a walled off area accessed by a pipe near the first battle of 1-6.
