Bounce Bros.

Bounce Bros. is one of Luigi's Bros. Attack in the game Mario & Luigi: Superstar Saga. The move costs four BP on Modes 1 and 2, and three BP on Mode 3. Luigi learns this move. This attack involves Luigi leaping onto Mario, who throws him into the air. When Luigi is right above him, Mario leaps into the air to grab him. The two then do a flip and Luigi slams into the enemy with his hands. The buttons that must be pressed are to throw Luigi,  to have Mario jump and catch him, and  again to have them both slam down. This attack is learned in Stardust Fields, along with Splash Bros.

If Mario and Luigi successfully execute the attack eight times, the Advanced version can be learned. In the Advanced version, Mario and Luigi separate, each tumbling toward an enemy. The commands are to initiate the attack,  to separate the Bros.,  again when Luigi nears the enemy he's targeting, and  again when Mario nears the enemy he's targeting. If there's only one enemy, the commands are the same, but the Bros. obviously will both target that enemy.
