3D Green Shell

3D Green Shell costs 4 BP to be used. The Attack Pieces to obtain the 3D Green Shell are found in Mushrise Park, which are required to all be collected to proceed through the game. It can only target enemies on the ground. The difference between 3D Green Shell and its counterpart is it hits enemies more randomly and Luigi initiates and ends the attack.

Upon using the attack, Mario and Luigi will run into the foreground, where Luigi will take out a Green Shell and kick it at one of the enemies. Mario will kick the Green Shell back at the enemies after it rebounds off the enemy towards him, and Luigi will do the same, this repeating three more times and each time both bros. move toward to the enemies a bit. After the Green Shell hits nine times, Mario will then kick the Green Shell towards Luigi, who blasts it at one of the enemies, ending the attack. If all enemies are defeated before the attack ends, it will end prematurely. When the shell comes to Luigi than press and when it comes to Mario press.

Striking three, five, nine and ten times with the Green Shell will yield an "OK!", "Good!", "Great!" and "Excellent!" rating respectively.
