Boobrie

The boobrie is a magical beast and a giant relative of the stork at 12' (3.7m) tall, that lives in swamps and marshes. It attacks by finding a tall patch of grass, hiding in it, and waiting for prey to come. The boobrie hardly ever attacks humanoids, instead sustaining itself on catfish, snakes, lizards, giant insects, and other wetland denizens. The boobrie, due to things it has been forced to eat in lean times, is immune to poison. It has some magical properties, though it cannot speak.
