Rocky Grassland is the first main course of Rebel Mario 64. It can be entered by jumping into the painting in the house with two doors and a Toad standing next to it.
Rocky Grassland is a big enclosure of cobble, grass, granite, and bricks. When first entered, text will greet you and tell Mario where to go. It will inform us about King Bomb-omb, the mysterious pipe on a mount, and the brick section where the Moai statue is.
There is also a well (which the creator of this hack calls it a fountain) that has a rope with a red coin hanging from it. Bevelled blocks (meaning Mario can't grab onto the edges) are everywhere in this level, and there's a pit of lava right by the brick section.
