Falling Ztars are extremeley powerful and NEW Bro Items in Mario & Luigi: Sibling Rivalry.
Like Falling Stars, when this attack is activated, a large star appears on the top screen, along with smaller stars next to each Wario Bro. The large star switches between yellow and purple, and the player must hit the button of the corresponding brother repeatedly. The player must also use the stylus to keep the aiming crusor focused on the large star, as it bounces around the screen for the duration of the attack. When the action command is finished, the large star will crash into a single enemy, followed by each of the smaller stars. Groups of seven small stars fall first, followed by individual stars, which do less damage.
