Rock Pikmin

The Rock Pikmin is a species of grey Pikmin that was discovered on PNF-404 during the first exploration done by Captain Charlie.

Description
As their names imply, Rock Pikmin resemble less of a plant and more like a chunk of graphite, their stems, arms, and legs having no outer protection like the rest of their bodies. Their flowers, like the Flying Pikmin, are colored a lavender hue.

The outer shell of the Rock Pikmin is highly durable, making the Rock Pikmin have much higher defense than the rest of the species, making them able to charge into hard objects without hurting themselves. This was a possible adaptation to protect themselves against the many predators of Pikmin.
