Nurgling

Nurglings are small (Roughly a foot high at best) disease ridden daemons who follow the Chaos Hordes into battle, spreading disease and causing fear. They vaguely resemble zombie Ork Snotlings, walking slime Balls or Buboes filled with dirt and pus. As their name suggests, they are daemonic creations of the Chaos God Nurgle.

Nurglings come in large Swarms or infest Champions, Demon Princes or Greater Demons of Nurgle - the Great Unclean Ones. It is said about Nurglings,'...they are the beloved children of Father Nurgle, eating his dirt, playing around his rotting carcass and toying with his bowels'.
