Description
True to its name, the Indigo Cave is an indigo-colored cave full of pink, glowing crystals and hot-pink lava. There are signs of man-made activity due to the presence of wooden fencing around the upper portions of the level and a bridge in the final area. The course is populated by Snifits, Goombas, Bob-ombs, and Fly Guys.
