Coprisand

When Scarub evolve into Coprisand, the dirt shell on their backs grows into a hard covering that's incredibly difficult to penetrate. People often mistake Coprisand to be just a rock, so when certain Pokemon try to bite it, the hard shell flinches the Pokemon. Many trainers can find success with this Pokemon due to its raised defenses, so they often use it against stronger trainers. These Pokemon are the natural enemy of Grubbin and Charjabug.
