The third ogre strongman brother, left behind on the third floor and presumed lost.
Reviewing what he knows about Herman the Fleet, Carl recounts that the three ogre strongmen from Grimaldi's circus were brothers: he met Areson the Wise on the sixth floor, Herman is now serving in the Princess Posse, and Apollon was left behind on the third floor. All three were once heads of a single three-headed Nodling that died and split long ago, making their separate existences strange enough on its own — a strangeness compounded by the fact that the same nodling was also turned into one of Carl's tattoos and has since been given flesh.
