Tall skeletal chattering-toothed undead ghouls — the last mercenaries left in Hungry Eyes, hired to drive for the party.
The Jikininki are level 25 undead ghouls — tall, skeletal creatures with chattering teeth, the same species as the janitor mobs on the Iron Tangle. When Rosetta and Tipid scour Hungry Eyes Village for hireable mercenaries, a pair of Jikininki are all that remain, and Rosetta brings them back as drivers for the party's coming Heat Three. Because they're undead, Princess Donut hisses at them and Rosetta warns that Rend must be kept away lest he bite one and die from consuming undead flesh — one of the meatball's standing weaknesses.
Grim, expendable hired help for a race the party can't skip.
Tall, gaunt, skeletal undead humanoids with perpetually chattering teeth.
Undead ghoul mercenaries hired as drivers for the party's Heat Three.
