The rock is covered in a thick layer of mud and has a variety of shapes and sizes, ranging from small stalactites and stalagmites to larger, more jagged stalagmite formations. The walls of the cave are dark and rocky, and the light from the ceiling casts a warm glow on the rock, highlighting the intricate details of the structure.
