Three Big Galoombas attack you on a platform surrounded by lava. It takes two stomps to beat them, but they can recover from the first stomp fairly quickly. If you are using Peach, it is possible to score extra lives by using her float ability to bounce off all three Big Galoombas in succession, giving them all a chance to constantly recover. So long as you don’t hit them while they are stunned, they’ll keep coming back. This isn’t the fastest way to score extra lives though! Finish off the enemies, then grab the Green Star to complete the level and unlock 2-5.
