Splash Bros.

Splash Bros. is one of Mario'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. Mario is the one who learns it. The move involves Mario jumping on Luigi throwing him in the air, then Luigi jump's under Mario, grabs him, and they both do a Spin Jump (with a huge flip at the end) to slam into the attacked enemy. The buttons that must be pressed are to have Mario jump,  to have Luigi leap under him, and  again to slam the enemy.

After successfully executing the attack twenty times, the Advanced version is learned. In the Advanced version, instead of jumping up to Mario, Luigi throws him in the air again. Mario then spins very fast, drilling into the enemy. The commands are to make Mario jump,  again to align Mario above Luigi,  to throw Mario in the air, and  again to drill into the enemy. The move does less damage than the regular version against most enemies, but does double damage against spiked enemies like Sharpeas and Pestnuts.
