From browsing Tumblr, I know a lot of Daily Bestiary fans are also fans of possession and body horror—so merry belated Christmas, kids, because this monster is for you.
The oolioddroo’s party piece is using her thought-siphoning tongue—you know, the one that can slurp up memories, skills, spells, or Wisdom—to implant her eggs into the brain of a sleeping or helpless victim. Eggs that then hatch as larva (still in that brain). Which the moth demon can track across any distance in the same Plane (safely nestled in that brain). And through which the demon can detect thoughts, modify memory, and cast suggestion (because brain). Worst of all, the oolioddroo can sacrifice the larva (and the victim’s brain—have I mentioned the brain?) in a kind of feeblemind bomb—a tactic that causes even the Bestiary 6 to break tone and refer to it as a “scorched earth” tactic.
That’s right: This is a monster so awful it makes even the rulebook itself stop and say, “Daaaaamn.”
An oolioddroo poses as a roving fortuneteller. Her magical abilities give her plenty of fodder for predictions, and she leaves a trail of infected or feebleminded victims in her wake. Normally such a humble disguise would be beneath the moth demon, but this particular band of rovers has long been welcome at a local magefair the oolioddroo intends to infiltrate.
Adventurers are asked to check on the niece of a patron. The young woman was married off to a stern landholder in a distant county, and in the intervening months her letters have grown strange and evasive. Should the adventurers take the case, they find the woman in decent spirits but acting oddly—as do many inhabitants of the local village and the surrounding district. Further investigation reveals the truth: Much of the town is under the control of an oolioddroo. But when the adventurers go to confront the demon, they find themselves ambushed by the village’s uninfected in habitants. The entire town has willingly devoted itself to the moth demon, and the infected villagers were merely a lure to draw the adventurers into its clutches.
Among a certain truly decadent and thrill-seeking set, oolioddroo eggs are a delicacy akin to caviar. The challenge is to consume and pass the eggs without falling under the moth demon’s sway. And since such eggs can only be harvested from the brains of an oolioddroo’s victims, this delicacy necessarily involves appallingly risky chirurgery or a hefty body count.

That second adventure seed has a very Hellboy feel to it, if you ask me.
