The Dark Young of Shub-Niggurath are horrifying, pitch-black monstrosities, seemingly made of ropy tentacles. They stand as tall as a tree (perhaps between twelve and twenty feet tall) on a pair of stumpy, hooved legs. A mass of tentacles protudes from their trunks where a head would normally be, and puckered maws, dripping green goo, cover their flanks. The monsters roughly resemble trees in silhouette — the trunks being the short legs and the tops of the trees represented by the ropy, branching bodies. The whole mass of these things smells like an open grave. They usually dwell in woodlands wherever Shub-Niggurath’s cult is active. (taken from yog-sothoth.com)
