I’m DMing Tales of the Scarecrow tomorrow. The gist is that a colossal tentacled monster lives underneath a farmhouse and perfectly circular cornfield and sticks its barbed tentacles up out of the ground to attack anyone in the corn. The monster is the size of the whole farm.
Prior to the attack, though, I want to use the farmland sounds (minus the animals) but then add a menacing gigantic underground something of a noise to suggest that something is there . . .
Anyone have a suggestion on what to use for this?
