The AD&D 1st Edition Fiend Folio was like the Monster Manual's poseur cousin, full of really weird and dumb monsters. There is some good stuff in there too, but it's not a book that i often flip through. So i was pretty amused to come across this for the first time, or at least the first time since i've seen Troll 2. As is often the case with Fiend Folio monsters, the creature is pretty dumb and i don't see how i could actually use them in a campaign. So don't worry, players. Nilbogism is not an epidemic in your world.

It's weird how it says nothing about how they are vegetarians that try to get around their vegetarianism by trying to turn you into plants so they can eat you.

i'm pretty sure normal goblins are treated with extreme caution because they'll kill you and rob your corpse, not because they might be nilbogs.

So the inverted Axis Roderick Kingsley was really the Bohnilbog.

I really like the word "Bohnilbog". Sounds Celtic or something. Now maybe i do need to introduce Nilbogism into my campaign.

I'm with you, Fnord, I don't see how you can use them in a campaign. Weird.
