Mario about to hit the red balls.
|First game||Mario & Luigi: Bowser's Inside Story (2009)|
Arm Center is an area of Bowser's right arm in Mario & Luigi: Bowser's Inside Story. Mario and Luigi visit this location on a quadrumvirate of occasions - the difficulty will progressively increase from task-to-task - in order to stimulate the muscles, resulting in an increase in strength, which will enable Bowser's ability to perform various tasks and will result in the progression of the storyline.
The mini-game requires Mario and Luigi to hit the balls of light back at Bowser's arm muscles; Mario will have to hit the red balls with his hammer and Luigi will have to hit the green balls with his hammer.
