Every Garden needs a gardener. And it’s no different for the Garden of Nurgle, which has this fellow attend to it. Horticulous Slimux is a Herald of Nurgle held in pretty high esteeem by the grandfather; so much so that some think he may be one of the first Plaguebearers ever created. Nonetheless, he is an old fuck that rides around on his Molluscoid Mulch everywhere like a mobility scooter.
Fun fact: Ślimak is the Polish word for 'snail'. Make of this what you will.
