Stairface Ogre

Stairface Ogres are enormous Thwomp-like enemy creatures wielding a stamp-like mallet found predominantly in Bowser's Kingdom, as well as the Metro Kingdom within Super Mario Odyssey. They are called the locals of Bowser's Kingdom within the in-game brochure. Their primary means of attack is to smash their staircase-shaped mallet down where Mario is standing, which allows Mario to climb up their mallets. Before swinging down their mallets, they telegraph where they are about to attack Mario. Stairface Ogres can be defeated by performing a Ground Pound on top of their head or by poking the yellow gem on their forehead while controlling a Pokio. After a Stairface Ogre is defeated, it makes a wailing sound and explodes. Its face bears a striking resemblance to a Thwomp or Whomp, though they seem to be based off of the mythological, which is sometimes seen as a Japanese counterpart to the ogre.

The mission "Infiltrate Bowser's Castle!" in Bowser's Kingdom specifically requires Mario to defeat a Stairface Ogre to progress. Additionally, Stairface Ogres can be used to break blocks, which is useful for revealing items (if any) inside the blocks.

Terrifying Gatekeepers
''Don't run afoul of the Stairface Ogres that guard this kingdom. When they spot an intruder, they bring their huge mallets down, no questions asked. On the other hand, you have to admire their tenacity and work ethic. The scars on their faces show that they don't give up easily.''
