Mario and Luigi Partners In TimeEdit
In this game the Green Shell is a Bros. Item, and is the first one used in the game. When only two brothers are battling it is used by pressing the A/X or B/Y buttons as the shell moves toward a bro. if timed correctly they will kick the shell towards an enemy and cause damage. They must continue kicking the shell back and forth until the enemy is destroyed, they miss pressing a button at the right time, or the shell is destroyed. With four Bros. it is the same except that one of the Babies ride on top of the shell and can press X/Y as they are near the enemy to deal extra damage.
