A malboro, sometimes called a morbol or a stroper, is a carnivorous plant that prowls the most fetid swamps and marshlands in search of prey. Its foul breath and glistening fangs have been the doom of many an unwary adventurer. Ravenous Horrors. A malboro does not photosynthesize like a normal plant, instead deriving all its nutrients from the creatures it devours. During daylight hours it will seek out and consume any animal smaller than itself, digesting them within its disgusting maw.
