This stage is very unique in that it is a labyrinth of caves in that players cannot kill opponents the normal way most of the time. Instead players should kill opponents via the Danger Zones all over the stage. Danger Zones' KO players over 100%.
In addition, there are mine carts that players can ride and hurt players it collides into. There are spikes that can rack damage and chests that spawn random items too.
