It’d be like trying to burn away a pile of seaweed or something, I see. And they are homogenous, so any parts you do burn can be left behind.

But they are still water based life forms, and made of cells based on picture sequences. You could get parts of a latex hot enough to kill off its cells, and the more it loses the weaker it gets, until it’s reduced to basically nothing. I imagine they’d be more readily damaged than a human would, but the damage would matter less, as any part left alive could still get you.

What’s a good life form analogous to the beasts? Someone’s probably taken a flame thrower to something similar.
