Roggenrola

The hexagonal cavity is its ear. It walks in the direction of sounds it hears, but if the sounds cease, it panics and topples over.

The hexagonal hole is its ear. Deep in that ear is an energy core, so if you stick your hand in there, Roggenrola will be very angry!

It was found in a fissure in a layer of exposed rock. The material that makes up its body is dirt from several hundred years ago.

It’s as hard as steel, but apparently a long soak in water will cause it to soften a bit.

When it detects a noise, it starts to move. The energy core inside it makes this Pokémon slightly warm to the touch.
