__NOEDITSECTION__ Magma Hole (Magma Hall in Japan) is a holosseum stage in Custom Robo (Nintendo 64), Custom Robo V2, Custom Robo (GameCube), and Custom Robo Arena. It is a medium-size octagon stage that has a sinkhole in the middle. When a robo steps on it, it sinks and magma rises up. You may choose to stand on the small tower in the center of the hole because it will never go beneath the magma.
