It looks like it's an area that have something to be careful about it... the lava that raise could be dangerous for players, so it's all of a challenge! It could be risky, but it should probably be fun, it's like if I can travel through a mine, but with excessive danger. Through it's pretty rare there's a fire stage that isn't a Bowser one, really. (But in Mario Party 8, the stage was in space instead of being a fire-themed one!)
