Let them blow up!

I've scouted out the area — and I saw the most horrible thing: these serpents, multi-headed or otherwise, are crawling from a hole in the hybrid farm's fence! Hundreds of 'em!
Just as I thought: these scientists have messed up again, made some kind of mutants that end up harming us! And the serpents that swarm around the fence are much bigger than those running around here! In short, looks like we're well and truly screwed!
Unless we manage to send them all on a date with Nih... But how?
Well, I've got an idea, {username}... We've started using a special kind of robot for tunnel-boring: they can be detonated remotely! You launch a drone, it flies smack into the middle of them, and then you blow it up — along with all these critters! And then we are saved!

I wonder if these serpents can fly at all?

Have you dealt with all of them? It means our construction site's out of danger! Hooray, this is a victory!
