is the second stage in the Dark Descent Stages
The stage opens with a few Doge Darks. When the base is damaged, Shadow Boxer K will appear, and will continue to spawn at a moderate rate along with more Doge Darks. This will repeat infinitely.
There aren't as many Doge Darks as on Eastern Cave, meaning you should have little trouble on this stage if you can take care of the Shadow Boxer K's.
