Developing further from shapless larvae the Other Gods display amazing variety of shapes and formes.
According to the quotes I gave these
*flute like vocal organs
* the top variety, has stiff membranes and heavy stalks that are probably capable of making the drum-like sounds.
amidst the muffled, maddening beating of vile drums and the thin, monotonous whine of accursed flutes; to which detestable pounding and piping dance slowly, awkwardly, and absurdly the gigantic Ultimate gods
H. P. Lovecraft, The Dream-Quest Of Unknown Kadath
Here the vast Lord of All in darkness muttered
Things he had dreamed but could not understand,
While near him shapeless bat-things flopped and fluttered
In idiot vortices that ray-streams fanned.
