In Pikmin: Decayed Leaf
The Smashgren is a species of slabben in Pikmin: Decayed Leaf. The creature seems to be a very large, mossy, clay cube, which serves as a shell for a large, green bug. The Smashgren will remain idle until Pikmin approach it. When they do, it will slowly lean over towards them and attempt to land on them to crush them. The cube will pursue Pikmin until it is damaged by Rock Pikmin, whereupon the Smashgren will pick up its pace and gradually move faster as the cube is damaged. This continues until the Smashgren's entire cube is destroyed. Small chunks of clay and a large, green bug will go flying. The bug will not attempt to recover and regenerate its chunks of rock; it will instead attempt to pick up chunks of rock and throw them at Pikmin to kill them. Any type of Pikmin can attack the bug and the clay chunks.
