Thanks for the info on the Unt.

Yeah, sort of like that. just like a neckhole with a bunch of tentacles that kind of form together into a writhing mass of grossness. It uses it's tentacle mouth to kind of envelop people into it when it eats. What a pleasant death.

I think, considering how big it is (100 feet, yeah?) I think shooting out nails tipped would be a bit unnecessary. I think just uprooting trees and throwing them would be better for forces on the ground. The acid-fungus and hivemind creatures would take care of any unwanted guests on the Threat's shoulders.

The fungus, I imagine, is like a conical sort of shape with a top part that sprouts from the top. It kind of moves around and detects movement and fires globs of acid or emits poisonous gas depending on the situation.  With all of the fungus together co-ordinated they could create a sizeable projectile with a lot of force behind it.

I can imagine a scene where a hover-craft gets nailed by some acid, and the acid just sticks to the craft and dissolves it's hull and engines until it spirals out of control and slams into the ground.
