Beast of Nurgle

Take a slug. Now give it two big stompy feet. Now added a big leering toothy humaniod face on top of it. Make it diseased and a lumbering sack of all the worst plagues/sores/open wounds you have ever seen. Make it smell like the worst toilet you've ever been in and congratulations, you got the barest idea of what a Beast of Nurgle must be like in person.

Oh but this great big nasty slime bag isn't evil. No, it just wants hugs!

A truly terrifying daemon created to horrify you in a way you didn't think possible, the Beast of Nurgle represents all the joy and happiness Nurgle feels in his big blackened heart. The Beast has the personality of a playful puppy and just loves making friends. Look at it slobbering towards you, it doesn't want to kill you. No it just wants to lick you all over with that pus weeping poisonous tongue it has.

While it wants playmates, those new friends of it's never survive long, either crushed under it's hideous weight or kill by the lethal viruses and poisons that make up it's body. Upset that their new friends stop moving after a while, the Beasts set off to find someone new to play with, already having forgotten about the crushed pulp it was just slobbering over.

Truly Nurgle is a sick old bastard.
