Roggenrola

Mantle Pokémon ^#524

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.

- Sturdy
  When this Pokémon is at full HP, any hit that would knock it out will instead leave it with 1 HP. Regardless of its current HP, it is also immune to the one-hit KO moves: fissure, guillotine, horn drill, and sheer cold. If this Pokémon is holding a focus sash, this ability takes precedence and the item will not be consumed.
- Weak-Armor
  Whenever a physical move hits this Pokémon, its Speed rises one stage and its Defense falls one stage. This ability triggers on every hit of a multiple-hit move.

- Sand-Force
  During a sandstorm, this Pokémon's rock-, ground-, and steel-type moves have 1.3× their base power. This Pokémon does not take sandstorm damage, regardless of type.

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.
