Bye-Bye Cannon

Bye-Bye Cannon is Mario's Bros. Attack in Mario & Luigi: Dream Team. Its Attack Pieces are located in Wakeport, and it costs 7 BP.

Mario and Luigi jump into a cannon. A randomized sequence of them blast out, there being three of each Bro. in the sequence. The player must hit and  in the same sequence Mario and Luigi came out as they land on the same enemy, and if successful, must do the same sequence backwards for maximum damage as they come down in the form of a large yet slowly shrinking Spin Jump the second time. The move seems to be inspired by the Cannonballer from Mario & Luigi: Partners in Time.

Description
''Memorize the order that the shadows of Mario and Luigi launch into the sky. As they land, press the A Button for Mario and the B Button for Luigi. If you get it perfect, they'll descend in the opposite. Stay focused!''
